## Overview

The Jim Dunlop M133 MXR Micro Amp Pedal is a compact, analog preamp boost pedal designed to add a preset gain with a single knob. Ideal for balancing output between guitars or enhancing lead signals, it features a red LED on/off indicator and runs on a 9V battery drawing just 9mA. Made in Benicia, California, this pedal preserves your tone while delivering a clean, reliable boost favored by top guitarists.

## Description

Product Description Adding a preset amount of gain with just a single control, the Micro Amp is a great way to boost your signal for lead work or adjust between two different guitars with unmatched output (i.e. humbuckers to single-coils). It can also provide a permanent boost in a long effects chain where signal drop off is a problem. Box Contains M133

Review: MXR - This is an excellent pedal and great for boosting signal for riffs
Review: Best clean boost pedal on the market - You really can't go wrong with this pedal, at the end of the day John Frusciante uses it and you can't really say much more than that. Simply put, it adds more 'meat' to your base tone, chords ring clearer and single notes sing longer and louder. Doesn't change your tone in any way per se, just somehow 'improves' it almost imperceptibly. It's a fairly subtle effect for the price admittedly, but in my opinion entirely worth it!

## Questions & Answers

**Q: I need a micro amp that I can run a mic through...anything available?**
A: I doubt this will fulfill your needs as it is a signal boost pedal that feeds Ito a guitar amplifier which then feeds into and drives a speaker ( as in Celestion ) for example.  The name micro has nothing to do with a microphone.

**Q: Good for an oasis and kings of Leon tone?**
A: This pedal simply boosts output  (Loudness) so will push a tube amp into breakup/distortion if your pickups/guitar volume knob will not, similarly distortion pedals. It is excellent at what it does though a little pricy. This will not make you sound like anyone, stomping on it is a bit like having an extra turbo charged  guitar volume knob .

**Q: is it true bypass?**
A: Clearly this pedal both is and isn't true bypass

MXR don’t disappoint, this is another well built, no nonsense piece of kit. It boosts your signal just as it should, with no added noise . It’s small, powerful and simple to operate, they’ve been around a long time, there’s a reason for that!
