Mine tends to make a crackly and scratchy noise when the sustain is turned up to full, but it’s dead silent with the sustain at less than halfway.

It could also be due to an earthing problem with some of the mains sockets in my house which just happen to be the ones my VC30 amp and pedals are powered from. these have been needing to be rewired for a long time.

Regards

Floyd
