Finally got around to getting this done this weekend. I gotta say, I was surprised with this... I knew my tone changed when I took it out of the chain, but now I can see WHY. The tone control is always in the signal path... kinda kewl. Now that I know that, I can use it to my advantage to soften my tone a bit before it hits the amp (I always keep my phaser at the end of my chain).

Thanks for your hard work David. Much appreciated.
Are those OTA-based stages 13600s, or are they 3080s and discrete buffer stages?
Here's my thread with the gutshots of the original pedal: http://www.diystompboxes.com/smfforum/index.php?topic=76704.0 (http://www.diystompboxes.com/smfforum/index.php?topic=76704.0)
I can pop up the trace of the factory PCB if anyone is interested. I can make it ready for transfer, and have a component "screen" prepared as well. Otherwise, I'll just save the web space. :icon_lol:

Doh! I forgot a couple things, I see... labels. OTA's are 13600's, U1 and U2 are uPC4072 HA.

Updated!
Well thanks all over again!
If anyone can explain the LFO for me, I would appreciate it. When I adjust the trimmer, one way lowers the sweep range, and gets rid of the fast top trip. The other way gets it sweeping normal (really long bottom, it seems to work the way the Tri-Vibe's LFO output looks... quick trip to the top and sweeps back down to the bottom), and in the normal range.
Then when I get to a certain point, I get a really sweet double-lope. It's a WHOoeeooOO wooeoo WHOoeeooOO wooeoo. Why is that? I want to exploit that... it would make an awesome switchable mod.
