All user reviews of 4/5 for the MXR M133 Micro Amp

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.

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.

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.

the mic amp is a pedal that is used to increase the volume when the triggers, it gives a bit more brightness and volume necessarily. Everything is analog input, output, a power supply, a potentiometer to adjust the desired volume level.

UTILIZATION

it can not be more simple as config.
no manual but not really necessary.

SOUND QUALITY

the rise in volume is clear it can not be subtle sonic degradation.
I use this with my guitar, but it should work the same way with all the instruments located in the same register.

OVERALL OPINION

I use it for 8 years.
value for money is excellent.
since I tried the RC booster Equally convincing is much more expensive, and it also has other options (bass / treeble, gain / volume)
If you have limited budget is an interesting pedal to increase the volume of part (solo for instance) without much effort for that, let's be clear after AC did not revolutionize the sound you have. If you want more grain should rather try to boost the ep more expensive but otherwise inducing him The thing is his least neutral, if you want a little transparency to the price mxr is for you.
