So my cousin has this older peavey Vyper rage 158, an the clean channel works fine but when he goes to use the lead/distortion channel there is none. Like it just makes the cleans louder an it's a tran's tube amp. Could the tubes be bad, because that is the only thing I can think of.
Transtubes don't have any tubes, so if you can replace the tubes I'll be amazed.
take it in to a shop of professionals that can see and fix the problem
how much gain do you have on it
Volume at 5 , pre gain between 3 and 4, post gain at 6.
