BB Preamp - is one of the best distortions I've ever had chance to play because it just helps your guitar sound and you can just go crazy man!!!!!
RC BOOSTER- takes your treble, middle and bass sound completely into another level (amazingly good, tasty tone)
ROBOTTALK2 = I've never found an envelope like this (chicken picking, bop phrasing, chord changing) you can use it in all situations and it sounds funky!
