JC 120 sounds thin

[rockman627]

I have one on my bench, and the 2nd channel sounds fine when vibrato or chorus is engaged, but sounds thin when switched to off.
I believe this is the appropriate schematic.
Can anyone point me in the right direction?

Are both speakers working when chorus is turned off?

I believe so, but I can't verify until I return to work on Tuesday.

I took Tuesday off, but your post have me the idea of checking the speaker phase. The black and red wires were reversed and also the green wire only looked connected. It needed soldering. After addressing these, the problem was resolved. Thanks for the help.
