So while playing on my Spider IV 150, it will start changing tones quickly like I am turning the knob. Will do this after 30 minutes to an hour of playing. Ani ideas?

Could it be that loose knobs are turning from vibration? I have read that some people add a small oring under the knob which gives some resistance to turning them. But I have also heard at least one time of someone having a simialr issue, which because ti was happening after some time of the amp being on, indicated overheating of a component (or possibly abad solder point).
