I built this and i have a slight bleed on the amp that is "off" This is only with high gain of course. Short of grounding the amps inputs with a different wiring scheme, is there a part I could change to lower the bleed?

Any way to remove this bleed short of changing the wiring scheme to ground the unused amp at the output past the buffer?

The crosstalk is probably happening in the switch, and I'm afraid the only way to probably get rid if this is to shunt the output to ground when it's not selected. That's the only way I've previously been able to get rid of it.
Behringer don't do signatures, but if they did, they'd probably stop working mid sen

Thats what i figured. i'm not totally sure how the switching actually works in this case, that's what's tricky for me...  Thanks...

Just threw this together in paint; it's how it works on a standard effect board. You can probably go from there :)

Thanks for that. I should have been more clear.I get how to wire it to ground unused output, I'm simply not sure how the default wiring works on the geofex hum free a/b/y. I'll probably just rewire it to fix the issue...
