I bought a Re-issue '62 Jap-Strat back in the late 80's and soon decided that I didn't like, or even use, the trem.

I was taking evening courses on a milling machine, so my project was to make a brass block that exactly filled the trem-block cavity. The bottom surface was flush with the 'floor' of the spring cavity, and the top was flush with the face of the guitar. I don't think anyone who didn't have access to a mill would want to pay a machinist to custom-make such a piece, and I've never seen one in any store. That's a pity, really, because the result was noticeably better than a hardtail, which simply has the bridge screwed onto the face of the guitar. That massive chunk of brass made major improvements in sustain and tone.

I found out a few years ago that the Yamaha SBG 2000 & 3000 LP-types both have brass blocks under their bridges, which is one reason they are much sought-after instruments.
