Have just bought a brand new Epiphone BB King "Lucille" semi-hollow electric. It's great......but..... I am getting a buzz back through the amp if I have the tone knobs anywhere above 2. It is there at any of the three settingsneck, bridge/neck, bridge. It is not noticeable if you mute the strings with your hand.
It is plugged into a Fender Mustang v.2 amp.
I'm guessing there could be more than one possible cause.
I know it's hard to diagnose online, but has anyone got any ideas what the most likely cause is?
