Stored in a home closet for three years. Losing my vision so closed and sold everything in my studio. Forgot about these. As is common on these the digital encoder selection knobs are jittery. I have seen replacement knob assemblies for it online. I know one of these was worse than the other. I will sell the pair for $150. I no longer have any way to play through them but they both worked when I shelved them. I had a third one that had had the knobs replaced and worked perfectly that I used regularly and sold with the studio . This is without a doubt in my opinion the best guitar processor ever made. Why Roland discontinued it I will never understand. At one point every studio in Atlanta had one!
