Roland Jazz Chorus-55 I had a JC-77 in the 80's. You buy this amp for its clean sound. Will also be a good acoustic amp when I decide what pup to put on my Alvarez. Built around 1987 and still sounds great. 2x25 watt amps into 2x8 Speakers. Very little pot noise and no hum or hiss so I wont be doing the interior clean/inspection that I had planned. $205 so it was cheap as chips. Previous owner was a drummer who was thining his amp herd. Good karma I think. The Chorus is wonderful, Reverb OK but my Neunaber wins and distortion will stay in the off position. Super for pedals. does not color the sound.
