All user reviews for the MXR M133 Micro Amp

A switch and a button, nothing more!

UTILIZATION

Could not be easier I think.

SOUND QUALITY

Can boost a clear, or cruncher, or bosster sound. And all this with style! Great sound, warm and dynamic.

OVERALL OPINION

I used for quite some years, connected between my head and my Peavey Classic 100 Xotic RC booster. I juggle between the two pedals or I clicks all 2. I have not found better configuration and that for years!
After that, it's all very personal. The pedals never react according to the same amp that is connected behind ... And the guy who plays on it!

RAS, everything has been said. Manufacturing quality and durability beyond reproach.

UTILIZATION

It could not be simpler because a single knob. The big problem with this pedal is that we want to put it everywhere so it sounds. So I'll take a 2nd to get one in front and one in the chain. Arf

SOUND QUALITY

I play with a standard strat and strat rise EMG SA.
The sound is simply HUGE. It has a light color in the top medium that brings so much heat that I have to play in his underwear.

Nothing flashy, not characterized control to the equa amp, shit; there is just a little je ne sais quoi in addition that brings a hell of fishing to your rig. Placed in front, knob at 11am, we really gaining momentum with an intake of discreet but effective gain, and already with a noticeable increase in volume. Really, it's very hard to turn it off once it has begun.

You push the knob in the last quarter and then it starts really cruncher, not to mention the onslaught of decibels that takes in esgourdes.
Note that the sound is slightly cramped. It is still very far from TS like in terms of "nasality."

It goes very well in reinforcement of a more hairy distortion, the micro amp giving the dynamic potential that could break said pedal (it is thanks to him that I did not throw my little big muff, and finally for the moment).

In the loop, the pedal proves just as effective. You lose the contribution of gain to win only on the volume (which is the goal), while keeping the slight coloration makes it really formidable. It transcends the sound on a solo or a riff that we need to attack with more fishing.

OVERALL OPINION

I use the micro amp for 2 years and have therefore placed at all possible, parts of my rig.

It's very subjective, but I find it gives the best of itself between 11am and 15:00. In real thing, is connected and gets a big mandala. I would not have imagined that a boost pedal, which is reluctant to buy a little at the beginning to its very appearance "utility" would be such a pillar of my sound.

You'll like her or not, but in any case it really worth trying.

Pedal 100% true analog bypass robust!

UTILIZATION

A Gain knob, a switch can not be simpler.

SOUND QUALITY

I would say it depends on the material used. I use a Vox AC 50 which is already a great amp. The clean Vox is already great but I use this pedal MXR Micro Amp between my guitar and my amp and then the sound is real nice and much more now (I use 40% of the winning race).
Namely, as I'm bassist, I also tested between my bass and my amp (ashdown mag 300) is ideal for bass solos, or even to move from its companion round sound more suited to funky slap.

OVERALL OPINION

I use it for 6-8 months now and this is the pedal that I use most in my pedalboard without doubt. The finish is obviously very strong as usual with MXR. Many complain about the location of the power supply but I do not mind it more than that.
The price may be too high for this simple hair gain but well worth finishing, simplicity and the final rendering.
It simply indispensable.

Pedal preamp, ie boost when the level is raised beyond a certain level. Analog effect as always with MXR. Classical case the brand, robust and compact.

UTILIZATION

More than easy to use configuration is the simplest it is possible to find an effect pedal.

SOUND QUALITY

Here is a boost acting on the volume level. EN according to its position in a chaining, its effect will differ: before or after a distortion, for example, the Micro Amp does not lead in the same way. Before, he played on the level that the attack distortion pedal to increase the gain, according to the same pedal it will just increase the overall volume without changing the gain. From there, so we will try!
The only adjustment available shows progressive and responsive allowing changes both subtle and numerous.
This pedal triggers an addiction quickly and once started it is difficult to pass. We must therefore show great discipline to not abuse it and lose it can do its interest: the effect of "surprise" created its inception.

OVERALL OPINION

True to MXR that I know both the range and quality, I have not tried anything else, and took advantage of an opportunity to acquire the Micro Amp. I use it sparingly, avoiding systematize its contribution. For if the effect appears to be relatively transparent, systematic use tends to equalize the sound.
I prefer to use it at the right time and this is what it is: kick boost needed.

a wonderful kick in the ass

UTILIZATION

has put behind a bass guitar ... a clav j have not tried the mic but it promises.
this pedal becomes an extension of your sound by amplifying the very musical
you always leave it in Action
anyway when we put the red c's all we can not go back!
c is the crack of the musician

SOUND QUALITY

put it between 12 and 13h and press
j have been bluffed with the bass more than guitar!
ca comes to life! AC added a fishing clear and powerful
and what a pleasure to see that the meters do not saturate seen so far
say that we buy things that cost so dear!
and that we bought in full! and end ca made soup!
that c is not baked! the crispy crust.
frankly the great quality that lasts for a reasonable price in an age when some elitist or are driven prices
a sure

OVERALL OPINION

buy two
it can be put at the beginning or end of string with the same magic sound different but very present musical and
do not make the mistake to consider it as one reserved for the guitar pedal
plug your bass signal ettout a little tired
it can be considered as starting too auxiliary
ca has the form of a pedal but c is much

Gigging and recording musician for 30 years but got pretty rusty on guitar for a long time (synthesizers took over) but recently inspired by the purchase of a Danelectro 56 Pro, have begun to play again. Currently trying to unlearn all my bad habits but having great fun with a 1974 Fender Vibrolux, Colorsound Wah Wah, Fender Jazzmaster and mxr micro amp.

I got mine in a boot sale for £5 in about 1995. I'm guessing it is a mid-late 70s model, without the red light.

I love the primal simplicity of this box - a rugged chassis, a decent switch, minimal logo and a single enormous black rubber dial (that'll be GAIN, then)....

The bottom is secured rather over-entusiastically by 4 screws and a metal plate, not exactly convenient but a lot better than a flimsy plastic hatch. After about the fourth battery change you'll probably be considering leaving the damn thing off altogether...probably not a good idea though.

The Micro amp does what it says on the tin really...it acts as a pre-amp stage to drive your amp at low levels without altering your tone. You get pure crunch without the fuzzy mess of most distortion units. In my humble opinion most distortion pedals out there are no match for an overdriven valve amplifier. Having said that I quite like a bit of fuzzy mess on the top once in a while ...Big Muff, anyone?

I would have to say the lack of the light is a bit of a pain. Generally speaking however, when this bad boy is ON...you'll know. Other than this little quibble there's nothing to dislike about this pedal.

Basically it's a block of steel. Built like a tank. Go on, kick it around for a while. Then check for broken toes.

The Micro amp is a very simple idea, executed perfectly. When you can't drive your amp too much (neighbours etc.) this will do it for you, without compromising your essential tone. I don't know how it sounds on other amps, but it sounds pretty fantastic with some hot valves!
I haven't been using a distortion unit since my Roger Mayer Mongoose Fuzz got nicked a while back, and am still considering adding a distortion unit, maybe a Rat or a Tube Screamer. But I see the distortion pedal as a kind of final stage for when you can afford to go over the top...then you can back it down to the Micro amp stage and return to your 'real' sound.
I'd just like to say I'm in no way a guitar guru, these are just my personal impressions of gear I own and use. Hope this helps someone.

I purchased my first MXR Micro Amp used on E-bay for about $60. I loved it but it was an older model without a light to let me know when it is on and without an input to allow me to use a wall wart. I bought another one new and paid $90 at a local music store.

I don't know if you can really call this pedal a guitar "effect" because it does not really color my tone in any way. What the Micro Amp does is provide the player with a gain boost. It has one nob that allows you to determine how much of a boost you want. This pedal lets me set my amps volume so that I am where I belong in the mix with the rest of the band and then when i go to play a lead or a subtle finger picking part I can step on the pedal and get that extra juice I need to move out in front slightly. Before i found the MXR Micro-amp i had tried to use an EQ pedal for the same purpose, i found that it was harder to manipulate and actually changed my tone rather than just boosting my signal.

Now that I have the newer model I don't know how I ever lived without the on/off light.

Made very well and it's such a simple concept that there is very little to go wrong.

If you play both rhythm and lead guitar in a project this pedal is great. You won't believe how such a simple function will add to the depth and power of your playing.

The MXR Micro Amp M-133 is the most basic pedal you can find. An input from your guitar, an output to your amplifier, a power jack and one volume knob, and that’s it. It’s very similar in structural design to the Phase 90 and it’s the same size: 2 ½” by 4 ½” by 5 ½”. There is a red LED that lets you know when the pedal is engaged and the pedal can be powered by a 9 volt battery or by an additional power supply.

UTILIZATION

This pedal is a one trick pony, but you are able to use that trick in many different ways. Basically all this pedal does is boosts your signal, and this will do different things depending on where you put it in your signal path. In front of a tube amp this pedal can push you over the edge if the amp is set on the verge of breakup, while retaining your tone. When used in the effects loop of an amp this pedal can provide a huge boost in volume if needed that is much cleaner than when it’s used in front of the amp. This pedal is also handy to match the volume of guitars. For example if you use low output single coils in a Stratocaster and then switch off to a hot rodded Les Paul there will be a change in volume during a gig. Kick this pedal on while you play the Strat and off while you play the LP and you wont have to be constantly changing your volume knob on your amp during the show

SOUND QUALITY

This pedal does not suck any noticeable high end off of your tone, so I would say the bypass is very good. This pedal is not an overdrive pedal, but can be used to push an amp into that territory if it’s placed before the input of an amp and it does that while staying clean and true to the tone that you start with. I mostly use this pedal in the effects loop of my amplifiers because I don’t need a change in preamp gain/volume, but I prefer a super clean boost of volume. This pedal works wonders here. What you put into this pedal is what you get out, only at a higher volume. I have experienced no loss of tone or additional noise when used with several different guitars and amps.

OVERALL OPINION

Overall I think this is a great pedal to have in your arsenal. It can push the front end of your amp, provide tons of volume boost in the loop, match signals for different guitars during a gig, and regain a quality signal if many pedals are used in succession. It’s built like a brick and it doesn’t take a lot of space on your board. I think it’s a great pedal, and I would suggest it to anyone who would need a boost.

This is simply a 7 band equalizer in stomp box skin.
I believe it is all analog.
No, no editing through pc, just 8 mini faders
This is only audio 1/4" connections
and it is not rackable in the traditional sense.


UTILIZATION

Setup is simple, plug your instrument in one end, the amp on the other and there you go. The sound editing is as simple as bending over and adjusting one of 8 faders. I have never consulted the manual, and never plan to. There is really nothing else to know.


SOUND QUALITY

The EQ is pretty good. Its a little noisy, but that is kind of a stupid deal with boss anyways. If you are really serious about EQ, you need a rack mountable, multi band equalizer. I use this on a Rhodes piano, and my Parker guitar. Works pretty good in getting some lows out and boosting highs to cut through the rest of the band for soloing. Works best after a distortion pedal to reduce the &; Like I said before, its a little noisy, I would never use it in a recording session, but in a live setting, no one would ever notice.


OVERALL OPINION

I have been using this for three years. I like its easy portability (its so small). I dislike the hiss you get when you boost the highs. This is really the only stomp box EQ I have ever tried. The prices for this pedal are decent. Its worth it if you need a clearer, brighter tone, or if you won't more low end say on a solo. Yeah, I would buy it again, its just so darn easy to use. But I love it, reproduce the sound of the amp by inflating the sound and giving it more body and thickness. You wont want to go with out this pedal if you can get your hands on one.

Analog Boost pedal.

In an input, an output Out. A single knob Gain: hard to easy!

UTILIZATION

The configuration is simple archi-.
Depending on the place attributed to him in the chain effect, different parts of the race will be the most appropriate single pot, once found your preference is the kind of adjustment that we will rarely touch.

SOUND QUALITY

This booster is not completely transparent. For those looking for it, MXR has released another great boost in collaboration with Bob Bradshaw / Custom Audio Electronics.
The Micro Amp meanwhile, brings a slight sheen in the treble, much appreciated! This is useful for a solo boost or just to add a little something personal has its sound. It's simple: mine is on almost constantly, and adds a dose of sacred fishing crunch of my Fender Blues Junior!

OVERALL OPINION

I use it now for about two weeks, on my guitars. I was not specifically gone to get a boost, is already well supplied with drives (TS808 Ibanez, Boss OD1 and Proco Rat), but an opportunity with a 39 euros, I jumped on it and I do not regret not at !
Of course such a tariff has the price / quality ratio is unbeatable, however, I think I can say that even new, this pedal is worth it.

I have tried the MXR Boost / Line Driver (excellent, the one) and the Electro Harmonix LPB1 (amazing, but apparently fragile). But the non-transparency of the Micro Amp adds some magic to my sound: hard to part with it now!

This is a clean boost pedal. I believe its all analog, but I'm not positive. It is the most simple a pedal can be, an on/off switch and a gain knob.

UTILIZATION

This pedal works exactly as advertised. It boosts the signal. Super easy to setup and use, considering its only one knob. I never needed to consult the manual so I can not comment on it.

SOUND QUALITY

This is designed to be a boost for leads or to help compensate between pickup outputs when switching between guitars. When you have your amp set for cleans or low to mid gain it works beautifully. There is a very distinct jump in volume with out any real coloring of your tone.

However, as you increase the amp gain the less effective this pedal is. With as the pre amp gain increases the pedal adds less and less volume. After a while it mostly just adds punch and saturation. Which is a very cool sound in its own right. It comes in really handy if you have an amp that need just a little extra push to get it into high gain territory.


OVERALL OPINION

If you're a clean to mid gain player looking for a volume boost this is the pedal for you. It can do significant boosts in volume without really touching your tone. Which is the entire point of a clean boost.

If you're a high gain player looking for a volume boost you should look else where. The jump in volume even with the gain all the way up on the pedal isn't significant enough to be useful. However, if your a high gain player looking for a way to add saturation and punch while retaining your core tone, definitely try a microamp out. It may be just what you're looking for.

A gain knob
switch
battery or mains power supply

UTILIZATION

It sets the level of boost with the gain and it knob sending potato

SOUND QUALITY

Superb, it produces a boost Fully transparent
Set up the sound of the original is preserved,
when the gain is cranked, really at an end of knob,
Legre a saturation appears, but this setting is to boost the windows exploded
point zero sound has a volume that itch that comes out of pedals is before or scrapes (in fact it is far more ffective at the end of string)
I use it mostly with a rglage medium or a little less than half to boost solos without too much difference in level with the rhythm

OVERALL OPINION

I use it for good 5 years, strong as a tank (requires MXR)
it works great.
Booster trs ffective to restore the juice after 35 pedals, or to calm a drummer too enterprising

The effect is a signal boostage intended to increase its volume for the lead parts, or to adjust the signal to the amp when changing guitar (humbucker / single coil). A third mode of use is to place this pedal constantly lit at the end of a long-chaining of various effects pedals to make the signal dynamics that would have degraded during the various in / out.

UTILIZATION

I think we can not be simpler ... the effect has a gain knob for the determination of desired level of boost. The connector consists of an in & out and a power supply sector. Of course a switch to (dis) engage the effect. Manual clear and comprehensive, even if there is not much to say, given the ease of use of the machine.

SOUND QUALITY

In fact, the impact of micro amp mainly depends on two things:

Its place in-chaining and especially the fact that it is placed before or after the distortion
-From the amount of gain you use on your amp.

For my part, I tried this pedal in conditions strong enough away from my setup (stock the store requires ...). I tried it on a fender twin amp saturated with a Wylde overdrive. The seller has exposed me as the idea that I intended to connect the front of my amp, he was placed in the micro amp overdrive and returning from the amp. And indeed, in this config, it works as described partout.Le signal is boosted in dB, so do not push the knob too far, it means more than enough for the lead.
But of course it did not work the same on my Soldano ... why? Well, simply because of the much higher gain of the head compared to the Wylde overdrive.
And I could not find any of this increase in power to be heard solo. While the sound became a bit more "punchy" but it was really too subtle to be noticed in a group situation. (If not ... no need)

But ... where I should be disappointed, I actually found that this pedal could be used even further, as a real complementary channel really useful.
Thus, by connecting a channel on my set wholesale crunch, I just hallucinated: A 0 it goes to nothing, and I rode the gain knob,
over the volume went up in proportion to the volume of the amp ... Normal, what, since there are no masses of distos ... but what do I have to fuck a lead sound with little distortion ... Huh ...? Honestly? O)

But the past 2 / 3 of the race knob, the term "gain" is (well ..: o)
its meaning: The swollen spectrum while becoming frighteningly accurate. I rang a huge canal in huge, really great for stoner rock rhythm that I like. His precise, crisp, no hum or whistle even at high volume, incredibly sharp. In fact, I found something in the spirit of the channel through orange found on the dual recto pages, a huge crunch like a little cocaine to the Foo Fighters!

This rediscovery of my amp allowed me to spend my 2nd channel will exclusively lead by adjusting the gain and volume accurately, which did not displease me!

OVERALL OPINION

I use it for a week and has already repeated three and a concert. I really have absolutely no complaints about this pedal that I use for it. I use very few of the clean (no I'm not a fag) and relatively few of the lead too (no I'm not Yngwie). And the micro amp allowed me to catch the ITS I needed for my large rhythm in my group so that it became my main grain used 95% in what I play. I tried many different things to boost my crunch (overdrive, booster, equalizer ...) but it distorted my signal and especially the grain Soldano is still fun, at the base (^^). But the sound is there ... ... ... enhancer is simply magical and extraordinary musicality.

Anyway ... I'm a fan!

The value for money is correct, although the system seems very simple ... but ... MXR's still the good stuff that sells easily at a price not too revised tumbles.

I certainly would not make that choice if I had tried this pedal on a high gain amp in the store because at the base, I was looking for a stomp box allowing me to boost my sound in dB for leads ... but with the experience, I really started to realize that everything is complicated considerably when it comes to boosting a high gain amp. The ideal is dedicated to another amp, or more realistically, another channel that alone.
And mxr, by necessity, led me to do that, and I'm really happy ... I had one here ... I have a 2CH 3CH ...

SOUND QUALITY

I use it with 3 amplifiers: VOX AC30, jcm slash and krank Krankenstein
in AC30 is monstrous (found in grain Brian May magnificent c)
jcm slash in it's great I have a 3rd channel (with the lead switched it looks like a single correct: sisi I assure you I have had this amp and I can tell you that it has very high limits better volume)
in the krank I use it as I do for Channel klean cruncher (not a twist that channel even with the volume turned up).
c for guitars les paul, telecaster, flying v, and frankenstrat.
my colleague try us with its strategy of 69 in organic AC30 WAS.

OVERALL OPINION

C simple solid as a tank with a transparent bypass
I think even in buy another to integrate it into one of my guitar
is found at prices quite correct new or OCCAZ.
go there with closed eyes you will not be over

Very simple analog pedal that can boost the signal of an instrument.
Connections: 6.35 in and out.

UTILIZATION

As can be seen in the photo, this pedal has a scwitch on-off and volume knob.
So everything is simple.

SOUND QUALITY

This effect is extremenent effective, I use it between my amp and my SansAmp GT2 LM (100% head lamps Soviet-made). As a group, I use it to boost my volume for solos. In addition to the volume, this pedal adds a slight grain (kind of enhancer?) Makes the sound more accurate, better defined.

OVERALL OPINION

The used since 1994.
I know of no other pedal as effective.
But although the guitarist who uses it uses the distortion of the amp, it is useless!
It must be placed after an effect module (amp simulator, distortion pedal ...).

Finally, it makes my Les Paul profondemment happy.
