so my epiphone valve special stopped working about month ago
the amp still made the noise it does when it was on and the tubes still light up.
i even got sound from the delay effect on the amp.

i thought it could be a power tube so i replaced it but she still won't go.

i recently got a marshall guvnor overdrive pedal and when i conect that up with the amp on 10 i get normal sound. however when i turn the pedal off or go straight from guitar to amp i get nothing.

does anyone know what is wrong

it only has one power tube which i replaced and i didn't think that the pre amp tubes could cause such a massive cut in volume

Input connection on the amp might be coming loose, weakening your signal.

Replace your preamp tubes or move the ones you have into different sockets, see if you can find one that's dead

It could also be a preamp tube, I suppose. I'd check the input jacks on both your amp and your guitar, though.
