The MXR Micro Amp is a straight booster. On single channel amps, placing the pedal in front of the amp it just increases the signal gain going into the amp thus driving the preamp harder and into more saturation. It works without colouring the tone, so no added treble or EQ changes. It delivers more volume but mostly gain if pushing the front end of the amp. When engaged in a series effects loop it can bump the volume way up for a solo boost.
