MXR Micro Amp (M-133), Pedal for electric guitar.
This device 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
Controls:
Footswitch toggles amp on/bypass (red LED
indicates on) Gain knob adjusts total
output volume when micro amp Is engaged
