    Hello folks. I bought a roland cube street amp. Playing a strat and Les Paul through it. It hums loudly with gain turned up. Clean sounds good. When I touch the strings the hum goes away. Roland tech. Says it must be a ground loop problem. But these amps don't have a ground prong on plug. They have a low voltage power source. Any help would be appreciated. I can send it back to M.F. under 45 day satisfaction guarantee. But its a hassle. I'm tired of f*****g with defective ****. I had problems with my blues jr. Thats why I got this solid state amp..signed disgusted
