I have a Marshall Valvestate 2000, had it for a few years. Today at band practice it started cutting out. It still makes noise, but none of the tone knobs effect the sound, so basically its running with them all at zero.

Anybody have any ideas what it could be. I'm hoping all it needs is a new tube, but perhaps someone here has had a similar experience and can enlighten me.

It's the tone knobs, they just don't add any sound anymore. Imagine turning all the bass mid and treb down, that's my amp right now.
