MXR M133 Micro Amp Guitar Pedal
The MXR M133 Micro Amp 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 dropoff is a problem.
Footswitch toggles effect On/Bypass (red LED indicates on)
Gain knob adjusts total output volume when micro amp is engaged
