Roland Promars MRS2

“It is maintained by a professional, and there are no operational problems such as pitch tuning, sound output from all keys, preset tone switching, and VCO, VCF, LFO, EG in manual mode.

The built-in battery has not been replaced. You can save the tone by replacing the built-in battery, but the battery is not replaced because there is a disadvantage that the saved tone cannot be edited. It’s a fun instrument to use while moving the knobs in manual mode.” Click here to visit listing on eBay
