I just picked up a Yamaha DG100 212 locally via Craigslist. I offered it for sale or trade here briefly, thinking it might be too complicated to use - but now I'm going to pull it off - because the more I mess with this thing, the more I'm starting to really like it. I bought a midi controller pedal today to activate the presets - and as I tweak and adjust to find my favorite pallette of tones - I'm getting more and more hooked. I'm interested in other DG users (DG 80, DG 1000 preamp, etc.) I don't mean endorsers (Holdsworth, et. al). Who uses these and will tell about their usage? For example, how does one set the expression pedal to be a volume pedal? Anyone?
