Built this today. Waiting on some matched FETs, but sounds pretty cool even with the first two outta my bag (2N5457's)
I added a 20kB Blend Pot, thanks Jon for the tips on how to do that. Also, has a blinking rate LED. Wish the LED faded on and off, it just goes like a square wave on and off...nevermind! It works, thats what matters.
Also added a vibe mod, which sounds subtly, but nicely, different to the normal tone, bit darker and "suckier"
Heres some badly taken pics
