“The auction is for a vintage Roland GR-300 Polyphonic Guitar Synthesizer. The unit is used but in excelent condition. It’s been working fine and before the auction, I just made sure it works with my G505 (not for sale) through all 24 pin cables (two of them currently in auction). I’ve been babied the unit for the last few years in clean, non-smoking and pet-free home studio.” Auction ended. Click here to browse on eBay.
