bin as I am not a fun note the settings when I did not like I can not say anything


NOTICE GLOBAL

How long have you use it? For one week

What thing do you like most and least?

Most: small but tough, no clutter, not too heavy, tube amp, it has the mouth (but I'm biased I love Marshall)

Have you tried many other models before buying it? yes quelques'un whose modern vintage peavey 5150 I finally tested for fun

How would you rate the quality / price?
I pay 500 € OCCAZ with revision and change lamps ...

With experience, you do again this choice? ...dropoff Window
Yes I am very disappointed in content..il do not .. I do not regret not having me listen to the reviews I have read on different fofo

All-tube amp 50w, 50w still for a while I light the light is compared to current 50w, I get to play with at home without having to master the one.
In terms of connectors nothing to say it is complete (effects loop, 2 speaker outputs, one 4ohms/16ohms switch, 1 switch high / low ..).
Regarding the reverb I find it very interesting and especially hot.

UTILIZATION

Regarding the use it is all bogus, 1 channel 1 channel saturation clean the problem is that there is a equalizer for 2 damage.
If you do not spend too much time to find a good sound if you have some experience in my opinion given the simplicity of the instrument.

SOUNDS

I play pop / rock / indie with a zoom g5 I plug in effects loop and an Epiphone les paul royal black (not terrible compared to my style but with a microphone and a gibson jones tv equipped with a Bigsby I do not envy the Stratocaster or Telecaster) the sound is really class when I combine the pedal and the amp I feel like an amp worthy of the biggest stage.

In conclusion this amp is cut out for a little while the style except metal and hard rock so I would say I put him 10 as they suit me completely

OVERALL OPINION

I bought some on a whim I needed a good amp as soon as I saw in used 350euros I jumped I'm not disappointed with the time we see it give. What I like best about this amp is its compatibility with the effects it looks like it is made for playing with effects, but it is not very good and also the versatility I can take me to angus young and then play the Arctic monkeys Vaccines or is impressive even if I think the G5 has much to zoom.

One last thing is an amp that will likely appreciate in value over time so better take care!

Amp loupiote: 12x7 3 and two EL34
50w 100w tube equivalence transition which
There are a rverb rather good, with this one hand SETTING THE canal. an effects loop with adjustable volume level, a DI out and exit HP compensated. A rglage Low / High also pretty good!

UTILIZATION

The config is simple, the sound is good, but no manual bought OCCAZ

The changes I made above:
HP Chang, the original G12T75 bofbof I half an Eminence Legend V12 Instead, the Celestion V30 in Shuya with more bass, and wao, what a pleasure!
MUCH more precision!!

Then the lights:
In V1: JJ / Tesla ECC83
In V2: 12AX7 EH
In V3: Sovtek 12ax7WA
Amplification in two EL34 EH
Chang's foot plastic rubber feet which absorb shock much better now, after the rpeter or lamps are hot this helps! I put the front foot more than behind, for a better angle (a semi-cutaway what)
Chang also reread the HP cable that has the amp for a larger section netement, the original cable is crappy!

Lamps backgrounds are crap you'll see the chang!
7 9 with no changes!

SOUNDS

Perfect for the PUNK! for rock, too, of Grunge, maybe for the very HxC but then college, because for the big sound it should not be inssufisant.

7 10 with no changes!

OVERALL OPINION

It's really a great amp at the base, with the changes (see above) it becomes a nuclear bomb for the punk!
A yes, the grips on the cot is a cado the sky! If only my C30 had also ...

Amp lamp (2 lamps and 2 preamp lamp power)

Power 25 Watts or 50, switch selectable alarriere

Connections:
Effect loop, line out, rec Compensated output, 2 hp output, then connect a second possibility den

2 channels, a gain, a reverb, a master channel

1 eq for lensemble, a marshall equalization in addition, you will understand

UTILIZATION

Simple configuration, so you turn the power stage, it waits 5 minutes, you turn the preamp and it is part, must put the eq and contour a bit much, as the preamp, master 5 or 6 and sound is set it all beh yes, yes marshallm c is as if I knew my damn, always there is that everything is simple

Good sound easy, yes, I connect as a boss OD 20 for Versatile distortion level and I get to have any sound I want with, cool, I mean the great frank, er France,

The manual? not know, but not really needed, but in case it is the site of Marshall

2009 Edit: I dropped the OD20, I use a dsormais VOX Big Ben Overdrive booster that I use the channel distortion, compressor and a "route 66" in between my effects. Significantly better than the od.

So, I use the little clear channel.

SOUNDS

My style, rather ska punk rock and metal as, well, my od between 20 and distortion and clear sound of the amp I have everything that I need.

I play a telecaster custom trick thing

sounds clear, pretty well defined, can be lacking a little bass, crunchable pushing the gain of the preamp, but niquel, we can do solo or manu al santana Tryo, sisi, or to clear punchy funk or ska

Satur good big sound, not big in the sense metal, but in the sense it takes up space is delirium, set in 25 watt, volume 5 of 10, I can do a concert without continuance guitar at 50 WAS niquel person, always well-defined, pushing the gain we get to the acdc sound or fury

with the pedal I can get more sounds kind Pleymo, everything depends on the settings of this one

2009 Edit: like I said I dropped the OD20 and sounds all cool to use overdrives "classic" for a more rock ...

OVERALL OPINION

Using 4 years

it is getting better, you can plug it directly on a table or something like that with the release Compensated rec, great for playing the black it is great for acdc the same, for a range of its most expanded, taking a pedal, if it is a AC lamp Frakass even more than that except that it rocks

value for something. occasion 450 euros, super, state niquel

You do again this election, I want my nephews c'ampli that I had, of course when I am peter from a tune I mesa boogie, with plenty of EQ options ... but already I find the his many thanks to my config od20 telecaster and amp

Edit 2009: APRS changing lamp (normal wear), here we go again, continued to his office.

This amp is terrible! I can't believe this thing has tubes in it. I thought at first I was listening to some made in China solid state amp that cost $150. I can't believe this thing has tubes. Not only was the tone flat and sounded like a can of bees, I thought that the thing was going to start smoking.

These amps were I suppose to be a hot rodded Marshall amp. Since most Marshall s were modded to high gain standards they decided to do this to rod version of the JCM800 and call it 900. The head version actually is tolerable but this ting is just trash.

SOUNDS

I have heard this amp with multiple guitars and every time is sounds like trash. I can't believe this was a good idea for the folks at Marshal to think people would like this. Well we all know that it wasn't a hit and Marshall tries to scrub it self of this tragedy. You wolud see a reissue of this amp I can guaranty that.

What ever guitar you use try something with a humbucker installed pickup. Otherwise this thing won't carry any beef. The distortion is nasally and buzzy. I actually sounds like a can of bees buzzing around. I couldn't stand listening to it longer than I had too. The tone as just flat out terrible and processed sounding. It sounded like a solid state amp.

OVERALL OPINION

This amp is a big miss for me. I wouldn't pick this amp up if you paid me. No idea what the going rate for these are and frankly don't care either. These amps need to be torched and put out of our misery.

I wouldn't recommend this amp to anyone. If you want a hot rodded MArshall tone and don't want to spend more than a $1000 then get a used Marshall JCm2000 DSL 100. You can pick those up in the classifieds all day for about $695. Or even get a used JCm 800 for a little more and slap a Boss SD-1 in front and you'll be fine.

that a tube amp, 25 or 50 watts, with a range of connection: between send and return for effects loop, a switch to change power

UTILIZATION

everything is simple on this amp and it get a good sound without tampering with the 1 hour has knobs! I board had no manual, but frankly, not need!

SOUNDS

This amp is derived based punk and rock! Issued the sound is very good (lamps forces), very rock ac dc style!
I play a jackson dx10d equipped with DiMarzio super distortion and fast track 2 and a zoom multi effects g92tt.
I like this earlier on the amps clean sound is good, the distortion typically marshall, round, hot and biting!

OVERALL OPINION

I have this amp for 6 months and it celuis I wanted!
I've tried a few amps but this is my first tube amp, I will not comment on comparisons to other of the same size!
what I like most is the sound of course but we also appreciate the handles on the sides, very practical, the knobs are fragile and of course, crachotent with time (it marshall) &%&%&% &% amps based punk
