Modding an Eh 12ay7 pre to be two cannel vs true bypass

Wondering if you might be able to reconnect the relay to the V2 grid which gets and buffers the clean signal. While V1 also gets the raw guitar input but switches its output at V1b. Alike the veritable Valvulator but with a switchable '800

I'm building another pedal along these line and see this is possible here now too.

It's not clear (to me at least!) what exactly you have in mind. How about you draw it up, post the dwg?

OK cool. I'll try and draw something up later and find my similar design. For now, guitar input goes to pin 7 of first tube. But the second tube pin 7 switches between V1 output and the input. The other relay switch is for MV volumes because the Marshall circuit will be louder.
