I recently bought a new grill from Fliptops to replace the grimy old one that's on my 70's V4B and match the one I got for my SVT cab. Problem is, I have no idea how to get the old grill off. I thought maybe I could unscrew one of the faceplate screws and pull it off like the cab grill, but it seems like the amp grill is bolted/screwed in instead of velcro'd like the cab. I saw someone on another site saying that you can unscrew the side screws on either side of the amp and pull out the chassis (which I tried and failed to do), so now I'm at a loss for how to get this new grill on. BTW it is a completely new piece, not just the grill cloth, in case that matters. Does anyone know how to get to the old grill without completely dismantling the amp?Any help would be greatly appreciated.
