Vypyr Pro volume cutting out

[Sybreed]

I've been using the Vypyr Pro 100 for about 6 years, and never had any issues until now.

Lately when I turn it on and start playing at my regular volume, the volume will fade out about 80%. Sometimes I'll turn the knob up to bring back the sound, but then the volume comes back and suddenly its way too loud. Sometimes I can play for 3 hours with no issues, other times it stays super quiet for the whole session.

Typical amp support would suggest its a burned out preamp tube, but this is a modelling amp, so I don't think there are any tubes in there... I've tried taking it apart and opening it up, but the amount of screws in awkward places locking it down makes it very difficult.

Anyone else know of this issue?

Since you turned the control and the volume jumped back, perhaps its the same as this:

it seems to be getting worse. the volume now is just fluctuating all over the place, getting real quiet, then going silent, then coming back, then going away. I have no idea whats going on

Well, did you try out any of the things mentioned in the other thread? These decoders are notoriously unreliable. In my Vypyr VIP 2 I usually just push or pull the decoder while turning so it will make better contact. Others have had success with contact cleaner.
