Frostwave guts

So, the signal would pass when bypassed, but not when active. Full bypass as evidenced by the DPDT footswitch, power light comes on, no output. No diagram, no desire to reverse engineer. (actually, I would love to clone one of these for myself, but I didn't try). So I decided to poke my organic temperature probe tool around inside (finger). U8 was hot, too hot for any normal operation. So I grabbed one out of my parts box on a hunch, soldered it in and away we go! I got lucky. I didn't follow up to see what U8 (TL072) was doing in the circuit. I figure some input was overloaded with a hot signal, or maybe it just died. Either way, here is a peek under the bonnet.
