Hey Matt G - if you can send me a board I'd like to give this a try as well. I'lll send you a message.Anyone built there CDB cd4007 overdrive yet?
I still have several boards available, don't be shy about asking! (Also: I think I'm going to make a revision that additionally has space for a surface mount Q1, allowing you to use either a through-hole or SMD transistor. If you're not afraid of SMD soldering, the SMD J201 seems to be readily available.)
Looks like I have band rehearsal on Thursday, so hopefully I'll soon have a report on using it in a live mix.
