Overview

The MXR M-133 Micro Amplifier Pedal adds a preset amount of gain, using a single control. With a guitar, this lets you boost your signal for lead work, adjust between 2 different guitars with unmatched output (i.e., humbucker to single coils), or it can supply a permanent boost in a long effects chain where signal drop-off is a problem. Power: Single 9-volt battery or Dunlop ECB-003 AC Adapter - Controls: Footswitch toggles amp on/bypass (red LED indicates on) Gain knob adjusts total output volume when the Micro Amp is engaged.

Works well on bass, too

By Stuart Holme

from Charlottesville, VA

Comments about MXR M-133 Micro Amp Pedal:

Very close to completely transparent, adds perhaps a touch of thickness in the mids, the highs are too close to call, but really good at "the same thing only louder". For the price it's hard to beat. Cleaner than the xotic EP boost when you run that at 9 volts, the MXR itself sounds great at 9 volts. I play active bass, so my signal is buffered, and I get tons of gain in front of my amp, have not even had to try it in the FX loop.

Soloing Boost solution

By Michael Gibbons

from Stockton

Comments about MXR M-133 Micro Amp Pedal:

Nice Boost ,does exactly what I want, Tone remains nice,Even feels like it enhances the tone instead of actualy changing it, a good thing. I'm useng the Acoustic G120H head as a back up or alternative to my main rig and needed a boost for my lead channel.works great with solid state head through effects loop. well built just as all MXR's have been for years. Enhanced boost

It's a no-brainer...

By cloudyeyetavern

from Springfield, MO

Comments about MXR M-133 Micro Amp Pedal:

If you use a tube amp, get this pedal. It's a really clean boost that squeezes that extra bit of juicy goodness out of your tubes. It's tiny, simple to use, and it gets your tone to the point you want it to be at!

Excellent item.

By Ed

from Killeen, Texas

Comments about MXR M-133 Micro Amp Pedal:

A fantastic addition to your sound. Just engage the pedal when you want more gain and volume, especially effective with a tube amp. Great sound, now I know why Jack White uses one as well.

Fantastic For Lead Boost

By dropd

from Mass

Comments about MXR M-133 Micro Amp Pedal:

The sound is superb. The clarity stays intact. It adds fullness but it's not muddy at all. This is permanent on my pedalboard. I run it in front of my amps distortion: Peavey Classic 30, and after an Elite Tone Fillmore thunder fuzz. The only effect other than delay in the loop and Rocktron Guitar Silencer. I can say that this pedal makes my amp sound much better than it already is! Don't waste your money on boutique boosts and don't try to save money getting the Electro Harmonix-LPB-1, you can't beat this.

Awesome!

By Hammy Whammy

from New York, New York

Comments about MXR M-133 Micro Amp Pedal:

I'm constantly changing around my pedalboard, to keep up with my band's ever changing set list, which requires alot of different sounds, especially being in an experimental band. However, this pedal is always on my board, whenever i change it up, its great for a signal chain boost, or for a lead boost for solos. Definetly a must have!

Great for Leads!!

By Leng Moua

from St. Paul, MN

Comments about MXR M-133 Micro Amp Pedal:

I bought this pedal a few weeks ago and used it at gigs right away. The pedal accompanies my current rig: American Strat, Fender Hot Rod Deville 410, Boss TU Chromatic Tuner, and a Jekyll & Hyde Overdrive/Distortion pedal. This pedal is NOT noisy, which was a major concern because I have single coils. The only feature this pedal has is more volume, and it fulfills that purpose rightiously. It doesn't take away from your tone when used, if anything, it makes the tone sound sweeter. If you are really lazy, the only drawback would be that you would have to unscrew the back of the pedal to insert a 9-volt battery. But I use a one-spot, which makes it easier. In conclusion, if you are looking for an extra boost on solos or leads, this is an awesome pedal.

...

By Charlie Adrianus

from oceanside, ny

Comments about MXR M-133 Micro Amp Pedal:

Pedal works fantastically, BIGGEST thing they don't tell you about it though is you MUST put it through your effects loop to get the desired result, otherwise in front of your amp it makes little to no difference in your sound.

Not bad!!!!

By MXRpedalsarethebest!!!!

from miami

Comments about MXR M-133 Micro Amp Pedal:

This pedal is wonderfull its a great little boost. Its like having an extra volume tone, I use it to boost some of my lead tones and it works!!!! This thing adds a great boost to my mesa express 50:5's overdrive when you combine the channels. The only problem is that the gain knob is not put in well, its glued on and it has come off plenty of times when changing the amount of gain. Otherwise this is a must buy pedal, it gets the job done real well!!!

Great pedal

By Joe

from Florida

Comments about MXR M-133 Micro Amp Pedal:

This is a great product! Clean boost that does not color your tone at all. I've read many reviews saying it does not give much boost in front of the amp and only is effective in an effects loop. NO WAY! I'm using it into a 61 bandmaster, last pedal in line and don't need to go past 11 or 12 o clock for a perfect boost. Highly recommended.
