Well no, I played though a JC 120 for a few years. Mid lined their dist/drive and would hit it with a compressor for more. Overall liked it, chorus was great.
Yes, the Chorus first came out on the JC amp and is the best Chorus on the market. Having said that I had a JC-90 and did not like the tone. It must have been the speaker used on that model because the JC-40, 60, and 120 all sound good. I noticed all but the JC-90 have silver domes, really?
