Overview from the Roland website:
The JC-22 Jazz Chorus delivers Roland’s classic JC clean tone and famous Dimensional Space Chorus effect in a compact amp that’s perfect for playing at home. Offering the essential features of the popular JC-40 in an even more scaled-down size, this versatile stereo amp is also great for intimate performances and recording. A high-quality reverb complements the onboard chorus, and there’s also a stereo input on the front panel for plugging in modelers, multi-effects, and stereo stomps. Built to the same standards of sound and durability that the long-running amp series is noted for, the JC-22 makes legendary JC tone more accessible than ever.
