Very recently my Vox AC15CC1 has made a very odd screeching noise, the kind of noise you get when scraping a fork across a dinner plate, not only is this very unpleasant but no matter how much the amp is turned down it still screeches like it is on full volume, i know this is not feedback because it happens even when my guitar is not plugged in, if any of you have resolved a problem like this, an explanation and some advice would be appreciated

Hmm I heard this sound once when the effects loop cables were wrongly connected! Try to disconnect all cables and then start the amp and see if it squeals. You can also do that test with guitar straight to input of the amp (one cable).

Could be several things:

- Bad tube
- Bad tube socket
- Bad pot
- Something else

I advise that you go the amp tech, it may be nothing that serious. Those amps have very simple circuits and there is little that can cost too much (if replacement in needed).
