Hi, I have a Spider Valve Mk 2 combo. When I turn the channel volume knob it also adjusts the effects knob next to it. So it turns the compressor and other effects as if I was turning the effects knob at the same time as the channel volume knob.

If I use the software editor and adjust the knob there it is fine. Therefore there must be some kind of connection that has happened between the two adjascent knobs.

Anyone know how easy this is to be fixed. I assume it has occurred through vibration.

Thanks for any replies.
