OK, guys, the Gristleizer is built up and works perfectly as far as I can tell. As Josh mentioned, there is some slight ticking when using really extreme bias settings, but pretty unobjectionable in my opinion.
One question for you: the way I currently have the flashing LED, it would have to be in addition to an on/off LED. That's how I think Josh has his. Is that a problem? I could probably figure out a way to turn the flashing LED on and off with bypass, but I'm hesitant to mess with the PCB right before ordering a big batch of them. I actually think having the flashing LED on all the time is helpful, but I don't know what everyone else thinks.
I need to change a couple things on the silkscreen layer, but other than that I think we're ready to go on the big order.
BTW, this thing is extremely versatile for a relatively simple circuit. Besides the multi-shape trem and VCF, the LFO gets up into audio speeds for nice ring mod/filter ring mod madness. There are also plenty of lofi, distorted sounds to be had (I had heard fears that updating the opamps would kill all the craziness - not something you need to worry about).
