Roland GR-55 with GK3 pick-up Excellent condition. Gigged a few times but of course being Roland it's absolutely bulletproof: no scratches or blemishes on the main unit. One very tiny scratch on the metal plate which attaches the GK3 to the guitar - you can barely see it (see pic). Great piece of kit - have had loads of fun with it. Best features for me were blending guitar and MIDI sounds, and using instant alternate tunings without having to touch my guitar - great on stage. Also can send the guitar's own pick ups through the unit so not limited to the GK3. The USB player for backing tracks, samples etc. is also really useful. I've made loads of patches for different songs / guitar sounds etc. Can leave these on if you like, or put it back to factory. Let me know after sale. Includes original PSU, all original fixtures and fittings for attaching the GK3 and manuals for GR-55 and GK3. It was previously fitted to my Strat (see pic). Only thing I don't have is the 13 pin cable hence price - these can be picked up cheaply on Ebay though. No box. Selling to fund new guitar purchase!
