Micro Amp M133 : MORE gain

Well, doesn't get more simple than one knob. Can add quite a lot of gain to the signal, actually. I use it either as a lead boost or to compensate for weaker signal. My favourite use is after fuzz/drive, at about 11 o'clock, with the guitar volume knob rolled half way down. Signal is nice and strong, and for a lead tone just roll the guitar knob up, no monkey business. This not a transparent boost, though, so if you are looking for this, better try something else. Rolls out some of the highs. My personal preference - I like it. Build quality is MXR - this will take up kicking around no problem. Knob is large and with the Dunlop rubber tyre it makes it very easy to adjust with your feet while playing. Now this is a lot of text for one knob. Very cool.
