I'm working on a Jaguar and Bass VI projects and as I've never installed one of these Jaguar bridges I decided to buy the cheapest bridge + tremolo combos from eBay and Amazon and test them out. Boy do I regret this! The first bridge came without thimbles, and now I'm waiting for replacement thimbles to arrive. The second bridge came with thimbles however they have a few problems: 1. The thimbles don't have bottoms. I've never worked with this type of bridge, but aren't they supposed to have bottoms so the adjustment screws can move the height of the bridge? 2. I read that the thimbles diameter should be either 3/8" or 9mm, and these ones are 10mm. 3. Once you put the bridge in the thimbles the fit is not snug and you can rattle the posts within the thimbles. Is this the way it is supposed to be? Now some installation questions. How snug should be the fit of the thimbles within the posts holes in the body? Should the fit be very snug, and if yes should I hammer the thimbles down gently using a piece of scrap? Any tips on how to drill the holes of the thimbles precisely, leaving no room for error? Thanks in advance for your help!
