Grailtone

OK, yesterday was like Xmas for me. I had two mods tweaked a little and two new mods and they all came back on the same day. One of the new mods was the Grailtone and I could use some instruction on it. There are a bunch of knobs on it and I am not sure where to begin, especially the variac switch. I know it will take time to dial this puppy in, but what is a good starting point. I think I would like to start with a classic plexi sound and then start taking it out from there.
thanks

Shoot me an email or give me a call for details. I'm a slave to the bench and R&D this week, super busy.

cc me on the email Rob, I need to dial in the module better

Rob emailed me some hints and I will pm you a copy if you want.
