Okay.. my amp is making some extreme crackling/static noises as of late. My amp and guitar are only a few months old. This problem seems to be getting worse as each day goes by. The static noise occurs mostly when been turned up loud and holding a note. Ive tried putting the amp into several different place in my house and the same thing happens. So, today i brought a friends amp over to test it out and the same thing happens. Ive tried 3 guitars on both amps and they all crackle and pop on my VOX ac15 and only 2 did it on the other amp. Also, my amp right now when i turned the volume down it made the noise by itself might have been the worse that i have heard so far. Please give me some advice. Thanks
