Ok, so I just bough a Jackson DXMG and it is awesome...I love it, but for some reason the volume knob like shorts or somthing when you turn it up. You can hear it crackle and sometimes when you get it all the way up the volume level starts to flucuate rapidly...then I tap the knob a few times and its fine. This might not be anymore than an annoyance right now but when I start doin' gigs its gonna look @$$. Anyone know whats goin' on?
