Watch out for DC on your bypass path versus whatever the tone control network floats at. I'd expect operating the bypass switch to create a loud noise.

I see what you mean, when I inserted that baxandall stage into roberts schematic, it wasn't really designed for that kind of tone stack.
I dont need huge gain, as essentially this will be used as a buffer stage with minimal gain from mostly digital sources and an RIAA stage.
What can be done to prevent noise when operating the bypass switch?
