MXR M133 Micro Amp Boost Pedal

Give yourself a boost when it's time for your solo. It operates with one knob that delivers the right amount of gain when you need it.

The MXR M133 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. Powered by a single 9 volt battery or Dunlop's 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.

bought this as a booster to allow for solos. So I tried it in front of my marshall dsl40, nada . . .nothing . . . no change . . . I thought it didn't work. So I put it in the effects loop and wow . . . fabulous . . . let's me step out for clean or distortion solos based on ny channel selection of my amp. Its perfect for effects loop operation for the marshall dsl. It may also work for other amps in same effects loop. Definitely a must have and no tone coloration either
