:mrgreen: oops.

I'm just used to that site having what I need. Should have looked.

Is the Road King about the same from input to master volume? It seems it should be, since it's a scaled down Road King.

OP, did you replace tubes?

I'm having this same issue. OP, is there any update for this issue?

I have tried swapping out Tubes 1,2, & 3 with known-good tubes to no avail.

Mesa support mentioned it may be a loose pot, which I will double check when I return.

Until then, any other ideas?

Thanks,
