@syhilly0107 Obviously Jud used different knobs over time. Before you do anything I'd call Rick at Signature Sound (he's one of our dealers) and see what he says. It really won't be worth it if you damage one of those controls!

i just spoke to him. thank you all for your help. for anyone who needs this, the only way to access the set screws is to remove the faceplate and the  4 plastic holders on the inside.. thank you all again..
