Hi I have a question about my Fender Pawn Shop Offset Special Guitar. Not a tele, so I hope it's ok to ask here. When I bought the guitar about 7 years ago from a store, they never gave me the original trem arm for it. I've never really used trem on any guitar but after all these years but decided to give it a try. I bought a fender jazzmaster arm online and I am trying to make it fit. It's kinda wobbly, loose and squeaky. I looked at some tutorials online, but the collet on my tail piece looks different from the examples I've seen on youtube. Mine has a tiny hex screw/plug in it. Is there any way to make these fit together snugly? Also, my guitar being a hybrid model doesn't have the normal jazzmaster rocking bridge. Is that needed for this trem system to work properly?
