Hard to tell without being there. Could be something like a computer or light dimmer causing noise, could be your effects loop jacks need to be cleaned with contact cleaner, could be a disconnected ground wire inside...if you rule out interference from something else, try cleaning the effects loop jacks. If that doesn't work, best to take it into a tech.

I'll try cleaning out the effects loop today before my show. Thanks for the advice, luckily its still under warranty so gonna head to Sam ash if that doesn't work out.
