  • Marshall Valvestate: NEED HELP!

    Amp turns on and LED work on amp and on the footswitch. no sound. guitar works. guitar cable works. speakers work. All work with another amp. If I put it on channel 3 the sound is very very quiet, i mean your ear on the speaker to hear it quiet. clean channel and overdrive channel do not work it seems. Amp was working one day and just died.

    Any tips, tricks, diagnoses?

    sounds like a component failed but I have fixed quite a few with bad solder joints which can have a very similar problem

        The fact that its power section is solid state could make any number of things. Could be a bad solder joint, could be a short in the wiring, etc. I would definitely take it to a tech and see if it could be fixed on the cheap. It might just be cheaper to buy another one, honestly. Valvestates aren't very expensive, and paying for labor may not make it worth it.

              Find a friend with good home insurance -drop it there for a couple days and then claim it was hit by lightning ! Then buy a good amp.

                I have a friend who uses a VS100 and it does the same thing. Through trial and error he noticed that when it went out he could fiddle with the loop level pot and it would come back. I don't know how or why this affected anything... but apprently there's some correlation there on his. Try it and let me know if it did anything.

                      loop level pot on the front of the amp? which channel did he try this on?

                        This.

                        I had huge problems with the FX loop in my VS8200.
                        The jacks they used in the VS series get dirty really easily.

                          I was thinking it was on the back, but the VS100 pictures on google have it on the front. I dunno man. Give them all a shot.

                          Peavey Impact and Sixtonoize seem to know more about this than I do, though. I'd take their advice first.

                              Just take a short cable with 1/4" ends and put it in the FX loop.
                              If it makes your amp sound all better, then the loop jacks are dirty.
                              If it doesn't make a difference, then you have a bigger problem.
