Ok guys, here is the deal. So the B2RE head arrived along with my 410HLF classic. Great stuff, awesome tone and chest pounding lows. The problem is if I play it for more than 20 secs, cracking noises start and suddendly the sounds loses all its warmth and I'm left with a distorted volume-less squeal. I took it to the local guitar shop and they had no idea what was wrong with it, since when I played it there it didn't make the noise. No, it's not my battery, tried it with 4 different basses, different cables. And I'm pretty sure it's something to do with the current. Anyone have any idea what's wrong with the current and what can I do to fix it?
