I was at GC several days ago for some tech work on my Fender J. While I was there, I was thinking about finally buying an effects pedal (effects virgin) and a new gig worthy tuner when I found the DigiTech BP90 bass processor with expression pedal...and built in chromatic tuner. I figured for the price of only $99.00, it'd be worth a shot. WHOA! I was really impressed when I played it at home! So many effects, sounds, chain signals etc. but the most impressive thing to me is the way it makes my back up bass (Dean) sound. It sounds like a totally different bass...A GOOD THING, lol. So far Im really glad I purchased it. Anyone else have this box and can you give any tips with its use? Thanks guys. Rock on.
