Living in Thailand and power supply rubbish. Getting a lot of ground hum on my 3 amps. All newer amps, Fender Super Champ XD, Laney VC30 and Fender rumble bass amp. All my guitars are pretty good, a couple even shielded, leads good. Its the hum where you take your hands off the strings and it gets worse. I read somewhere you need to use 3 pin plugs but that doesn't seem to make any difference. In any case earthing here in homes pretty sketchy, sometime non existant. I have about 6 guitars all doing the same thing, single coil and humbuckers so its not a guitar problem. Any other way to get around it? I have had hum from lights etc before but this is a bit worse than that and we don't have any flouro fittings in the house. Proximity to TV's, computers a problem?
