Sound Pure's Take
Condition: Used, Excellent
SP Luthier Notes: From the collection of our luthier. Both the guitar and the synth unit have been serviced and recapped.
This Roland G-303 + GR-300 bundle is a rare slice of true analog synth-guitar history, built for players who want inspiring textures you simply can’t fake with modern gear. The G-303’s comfortable 24 3/4" scale and dual humbuckers make it a solid, familiar-feeling instrument, while the GR-300 delivers fast, harmonically locked analog synthesis with vivid filters, detune, and expressive vibrato—all with that unmistakable vintage warmth. With guitar, synth, or blended output options, this rig is endlessly creative for recording and performance. Collectible, musical, and genuinely iconic, it’s a smart long-term investment for adventurous players and serious gear lovers alike.
