Cave dweller debug help

[otsismi]

Been troubleshooting a cave dweller I built the other day. I'm getting very low guitar signal through the effect but no delay. Pots do nothing except raise and lower volume somewhat.

Using an audio probe I followed the signal from the input to LPF1-in on the pt2399, from there I can't find the signal anymore. LPF1-out does not have a signal. Is the chip fried? Maybe a solder bridge to ground? I've inspected the board extensively and can't find anything visible.

Help!

Can you remove the IC and get audio? Delays I believe are the only ones you can do that with. Also have you tried different chips? Is your soldering good? What are your voltages.
