eesh, well, it's yet another uninspiring advice thread from me... sorry to say... I own A laney HCM120... 2x12... The left cone seems to be ratteling, or something behind it at least... the ratteling isn't really amplified, but it is loud and will get picked up on a mic thats up against the cone, unless the sound guy can put a noise gate on it at my up coming gig next week, I'm pretty much screwed aren't I? If I take my amp apart, does anyone know what is likely to be the problem? I don't really know what it should look like when fixed, so when broken, god knows.
