hi just bought a 89 jcm800 4212 combo. its in horrid condition, everything works electronically (apart from 2 pots which are buggy). i have pics of the chassis, but i dont know how to post them. these are the things i want to do. re-tolex re-grill cloth re tube (i want to put in the tubes that zakk wylde uses) 6550?. i also want to see if i can get a replacement front panel, were the knobs are. i doubt i can get one but mine is all scratced up. any comments or tips on these projects? thanks all!
