Ibanez dm1100 digital delay wet channel stopped working

[jlatrace]

I have an old dd by ibanez model dm1100. Last week the wet channel went completely silent, the dry channel works perfectly in both mic and line level settings. Does anyone have a schematic? I've checked with ibanez without any luck.

I have already changed the power section filter caps to eliminate that possibility. I suspect an opt amp but without a schematic it's difficult to follow the traces to ID the IC's in the wet circuit.

Thanks for any help.
