Schematic Help

Can anyone tell by this preamp schematic(pg 2) if the guitar channel is part of the tremolo circuit ? The "canon connector" and the TRS input, both "stereophonic", are for an accordion. I know the tremolo works. If I plug a mono guitar cable into the stereophnic input, I can hear it, but not so with the guitar and instrument inputs. With or without the proper footswitch.

Interesting. It does not look like the guitar input goes to the tremolo circuit.

Fair enough. thanks Bongo, but what about the Instrument input ?

Sorry, I meant to say both/neither of them.

Ok, thanks. A tech has it and I told him I wanted to get the tremolo and reverb working on those channels. I thought is was a footswitch jack issue at first. I'll have to call him and tell him not to mod it. Instead, I'll see if he can put an fx loop after the preamp and get a Peavey Valverb or something.
