I've completed my Sea Urchin and it works except that I get a serious volume loss when I engage the effect. So much so that it is unusable this way. Everything works like it should except for the volume loss. My PT2399's were locking up so I have tied pins 3 & 4 together as suggested elsewhere. The voltages all look good on both chips and the regulator. Are there any components I should check or swap out that could be causing this? Or could this be a bad batch of PT2399 (from Tayda). Thanks for any guidance.

Typically it's a resistor value that's off, like 100k instead of 10k for example. That's the first place to check. Ugghh I know what a pain.
If it is also the dry signal, look at the resistors around the opamp. The one i built is definitely unity volume.
You were right Jimi, I had a 39k in R3 instead of 360k. I usually measure the resistors before hand but obviously I missed this one. Hopefully swapping out will correct it. Thanks again guys!
Do keep us updated
That fixed it! Sounds awesome now. I'll post up when I get some pics.
