Moved from my other sale in the Amps section: Roland GR-20 guitar synth unit with GK-3B BASS pickup. Tons of cool synth sounds! Bought new in 2010 and used sparingly at home. Gigged once in 2010. Will fit all 4-, 5- and 6-string basses, although please note that I would not recommend installing on a bass that you're not willing to deface a bit. I chose to screw it directly into the body of my jazz bass, which worked great. The adhesive option was not very effective. Anything with an archtop would also be tricky. Original box contains GR-20, GK-3B bass pickup, 13-pin cable, tools and screws for installation, manuals for GR-20 and GK-3B, power supply. ASKING: $400 plus shipping. No trades.
