I decided to sell my Roland GR-20 guitar synthesizer, because recently I realized that I am barely using it. The cool thing is that its new owner will get a free Sonuus Guitar to MIDI converter worth of $129USD, so they won’t have to mount the clumsy GK MIDI pick-up to their guitars. The unit is in mint condition, comes with full set of cables and power supply. You can find more information about the synth on Roland’s official page, here’s the promo video, and on this page there are a few photos of my own GR-20. Hurry up, if you wish to get something really cool about your guitar. The price is $500USD (the street price for a new item is $595USD), you can purchase directly from the eBay listing. Do not forget that you will get a free Sonuus Guitar to MIDI converter!
