MXR Micro Amp Booster

Product Description

A versatile pedal for boosting your signal into your effects chain, into your amp, or for juicing your guitar's signal when you want to solo!

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.


  • Footswitch toggles amp on/bypass (red LED indicates on)
  • Gain knob adjusts total output volume when the Micro Amp is engaged.
