Need a Layout for a High Gain channel switcher

[JustMike]

 I successfully built a couple of Marshall style amps but now I want to build a channel switcher with full tmb & master volumes on both channels. Are there any layouts or even kits out there? I tried a google search and couldn't find anything.

No layout, but it will keep you up late If you want to study it
