Hi, I recently bought a Roland Cube 80X.
It has a very anoying sandy like sound when I use gain. Only if I play a string.
I have tried everything, plugging it into a different power socket, using a different guitar, (Fender US strat and Tokay love rock) unplugging all wireless equipment,
Changed input cable, etc. When I use a headphone the amp jut sounds great.
I took it to the dealer were I bought it and no problem over there.
Does anybody have an idea what could be the problem??? I am getting desperate!!!
