My only amp (a crate 15w) has started randomly cutting out. About 3 times every minute for like 5 minutes, and then its perfect for about another 5 minutes or so and it starts randomly cutting out again. I switched the cable and it still happened, and i havent had a chance to test out my guitar (epiphone) on a different amp. I also tried different each pickup with the pick up selector, but the same thing happened for all of them.

If you know anything about this problem please tell me
Maybe it's the input jack on the guitar.
