MXR Micro Amp M133

Pedal Preamp

Guitarists never get tired of looking for ever-better pedals to achieve their perfect sound. But what if the amp actually sounds perfect, but needs just a bit more Gain? Overdrives and treble boosters would bend the frequency response which, in this case, is not desired. For precisely this, the MXR Micro has been the right thing for many years - without distorting the sound, the amp gets exactly the kick that was still missing; Ideal for bringing out the leading sound from old Marshalls, Fenders and Vöxen without distorting their beloved characteristic sound.

  • Adjustable boost
  • Perfect for switching between guitars with unmatched output
  • Great for use with long signal chains, or anytime signal drop-off is a problem
  • Knob for gain, status LED
  • Hardwire bypass
  • Sturdy metal housing
  • Operation via optional 9V battery or optional 9V power supply unit (available under article nr 409939)
  • Made in USA

MORE gain
georgebranekov, 14.04.2020
Well, doesn't get more simple than one knob. Can add quite a lot of gain to the signal, actually. I use it either as a lead boost or to compensate for weaker signal. My favourite use is after fuzz/drive, at about 11 o'clock, with the guitar volume knob rolled half way down. Signal is nice and strong, and for a lead tone just roll the guitar knob up, no monkey business. This not a transparent boost, though, so if you are looking for this, better try something else. Rolls out some of the highs. My personal preference - I like it. Build quality is MXR - this will take up kicking around no problem. Knob is large and with the Dunlop rubber tyre it makes it very easy to adjust with your feet while playing. Now this is a lot of text for one knob. Very cool.

Built to last!
21.04.2015
I'm writing this review now on 21st april 2015! I bought this pedal in July 2007! I still own it!

It has done me proud, never let me down and I highly recommend it to anyone and everyone. Such a simple piece of kit, one knob does it all and its perfect.

I used it in both my acoustic set up and my electric set up.

It runs on 9V or you can use a battery. I run it on the 9V as its requires unscrewing 4 screws to access the battery compartment.

So to summarise, having owned the pedal for 8 years, it is an excellent piece of gear for anyone wanting a boost. When you bring the knob up around 3 o'clock it adds a little gain but not too much to colour the sound, enough to boost your tone with a little added grit. I use it set at around 1 o'clock with the acoustic guitar to boost for solos and it sounds great.

This was my first purchase from Thomann and I have since come back many times. I would happily recommend both this product and the excellent service from Thomann!

surprisingly handy little pedal that should feature on every pedal board
Graham K., 25.05.2013
the MXR micro amp is a handy piece of kit.

mine arrived very well packaged in a good quality black box. once unpacked i found a very high quality pedal, the case is made of thick metal, the dial is good quality as is the switch.

its designed to boost your signal, but you can use it for way more than that, on large pedal boards, it helps keep your signal strength high. you can also use it to make yourself louder at a drop of a hat, and you can also add a bit of grind when you turn the gain switch to the max

i personally use it to make myself louder on stage when going into a heavy chorus.
being able to ramp up the sound level really helps to get the fans attention. and having the power to change your volume level without the sound guy makes life so much easier.

if you were to get just one pedal, this is the one i'd recommend, its simple, its incredibly diverse in its use, and the quality is a cut above all my other pedals.

Does the job
Callum Fogarty, 14.02.2019
I put this on my pedal board as a booste when playing solos and it does this perfectly. I have it set at about 10 o clock and that is all you need. This pedal can go very loud.
