Roland G-505, GR-300 GR-700 1982 - Sunburst

A legendary, fully operational piece of music history: a complete, plug-and-play Roland 24-pin analog guitar synthesizer rig. This package includes the iconic Roland GR-300 "Blue Box" floor unit, the highly sought-after Roland G-505 Strat-style controller (built by Fujigen), and a genuine, fully functioning original 24-pin connector cable.

Finding these individual pieces in working order is rare enough, but finding a completely matched, fully tested, and verified system eliminates the guesswork. This is the exact setup favored by Pat Metheny, Adrian Belew, Robert Fripp, and Andy Summers.
