IT WORKS!! HAZZAH!!
Ok, now that I got that out of my system, I can say that I am another verified user of the Tiny Tremolo. Turns out that this circuit really doesn't like superbright LED's, OR the VTL series Vactrols. They all make a popping sound on the peak of the tremolo, so I made a vactrol from a radioshack LDR that rated around 1M and a normal yellow LED. Sounds pretty sweet.
My thought now is that since there's a small volume drop, instead of using a 2PDT switch, you could use a 3PDT switch and route in a buffer/booster when the effect is on. I think I'm going to give this a try, and then squeeze it all into a 1590A enclosure. Thanks for all your help Rob! Can't wait to get it loaded up in a box now.
