What could be wrong with this old effects box? Analog Processors (HW)

What could be wrong with this old effects box?

I have a Yamaha Rex 50 multi-effects unit that I've used for a while. Just recently, it seems to have gotten a little bit screwed up. Whatever signal is going through it comes out thin, fuzzy and distorted and the output is very low, making it pretty much unusable. You can still hear the sound and whatever effect is selected, but the low output and distortion is still there.

Any ideas? The unit is Japanese, straight from the eighties, and of course all digital. I opened it up but couldn't see any disconnected wires or anything of the sort. But there aren't even many wires to begin with! Is there any chance it's an issue with the power transformer?

Any guidance would be greatly, greatly appreciated.

did you check the solder pads at the output jack for "cold solder joints" or loose solder joints?

while the guts are out you might as well check the other solder pads to.
