I have a Roland GR-55 Guitar Synth and a GK-3B divided pickup for sale together or seperate. I have misplaced the manual and box. The manual can be found online http://www.roland.com/support/article/?q=manuals&p=GR-55&id=59105308 It has been lightly gig'd about a half a dozen times but is otherwise fairly mint. The pickup has paint scratched off a little on the top from the strings even though I tried carefully removing it from the bass it was on. I'll take $450 plus shipping for the GR-55 and $125 for the GK-3B. $600 for both plus the 13-pin cable. I just don't use it, nothing wrong with it, tracks bass better than the older models and sounds great. Prefer Paypal. Will entertain possible trades for Eventide pedals.
