I was rooting thru my trunk of abandonded cables, broken pedals, dead strings etc. yesterday and came across the old GB-2. Plugged it into the PA and -voila -it still worked. I used to use this thing a lot...my teacher would program riffs in it for me to practice and i also used to find it helpfull for working on tone up to volume. Of course the manual is long gone and i cant remember how to program it. Anyone know where i can find one. Looked on the Kawai website but could'nt find anything there.
