The MXR M133 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 two 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 (sold separately)
- Footswitch toggles amp on/bypass (red LED indicates on)
- Gain knob adjusts total output volume when the Micro Amp is engaged
All pedals - one year parts and labor warranty.
