Howard!!!
Congratulations on the wonderful amp. The most discerning players have JC120s (like me

).
The tone is anything but sterile. I even like the 70s distortion (occasionally). In a pinch, the Jazz Chorus doubles as an acoustic amp.
Lately I've been using my small tube combo a lot but some songs really need the Roland.
Now you need an A/B box. Marty Willson-Piper (most notably of the Church) used a JC120 and Vox AC30 in tandem for years. You may revel in that rich sound. Use your 360V64 -run one out to each amp. Dial in the sound of the Elysium Fields!
The Roland is equally adept at clean and effected tones. I love the sound of my 1997 through a squashed compressor into my Roland. **sigh**
Anyway... glad you finally got it! When people hear it, they always comment on how good it sounds.
Cheers! Noel
