Will the Boneyard be dual or single channel?
I had planned on it being 1.5 channels with switching between two gain pots but actually I think I could just do two channels, each having a separate volume output but share the tone control. I think I'll do that instead.
-------------------
I couldn't let go of the Graphic Fuzz suggestion. After listening to some clips I decided it's something I want to build so I took a pass at it. The layout actually was easier than I though with maybe the last 5% of routing getting a bit hairy. Two areas I'm not yet sure about are the power and switching.
The power is a 12v dual rail so I actually put on two options: one using a charge pump and 12v PSU to get the -12v rail and the other using one of the Murata DC blocks and uses a 9v PSU. I think probably either will work fine since the only question is how much juice the negative rail needs. I don't think it's going to be more than 100mA!
The other was whether or not to use the original FET based switching. I decided to stick with that for now. I'm pretty sure I know what to do to convert it to true bypass but I think I want to at least try the FET switching out first.
Anyway, here's the first pass at a layout. The eq bands are 9mm plastic shaft pots at the top. I like this arrangement since sliders are pretty much out of the question.
