i just got my svt 810e the other day. first off...the improvement was drastic over my peavey 8x10. but that's just my opinion. anyway...i am having a problem though. in the lower left corner, there is a rattling sound. like something just may be loose or something. i'm going to email ampeg about it, but i wanted to know if you guys knew how to take the grill cloths off these cabs? do they just pop off? please let me know. thanks.
