MXR M133 Micro Amp guitar pedal adds a preset amount of gain dialed in from a single control knob. MXR M133 Micro Amp lets you boost your signal for lead work, adjust between 2 different guitars with unmatched output (i.e., humbucker to single coils), or supply a permanent boost in a long effects chain where signal drop-off is a problem. M-133 Micro Amp powers from a single 9-volt battery or Dunlop ECB-003 AC Adapter. MXR M133 Micro Amp features footswitch control, which toggles amp on/bypass (red LED indicates on) plus a gain knob to adjust total output volume when the Micro Amp is engaged.
