Look at the mixer IC. It generally does tone control/balance/volume.
Cost about $4 to replace. If there are any discrete transistors, and
I doubt there are, try tapping them with something non-metallic and
see if it affects the sound. Otherwise, throw it away, ain't worth
your time.

It's a back-burner project, just something I've been tinkering around
with in my spare time. I'll check the mixer IC tonight.
