I have a Vox VT40+ that I bought a while back and don't use that often. When I do use it, I notice what can only be described as a 'rattle' or some kind of hiss. Seems to go down/lessen if I turn the treble down but then I don't have any treble control.
Any ideas as to whether it can be solved or reduced in some way?
The amp itself is great - plenty of options for me, plenty powerful enough for home etc. - just wish I could get rid of this annoying rattle.
