This pedal picks up on GAIN where the Sex Drive left off. The Mucho Boosto IS based 100% around the Sex Drive circuit, with a few changes in the Gain, Tone and Compression. The GAIN is obviously much higher. With the LEVEL up all the way, and the GAIN down, you can achieve Sex Drive style clean boosting, on a limited scale. The opposite, of course will give you the most gain all the way to violin like sustain. The TONE circuit is much more active than that of the Sex Drive, due to the more aggressive sound, and not going for transparency.
