Re: Where can I get a fender vintage ri trem?
This is from the page where it tells about all the strat parts...not sure why he didn't put this info on the block details page. Sounds like the original blocks were rolled steel, then over the years they got cheaper.
"Callaham Vibrato / Tremolo Replacement Blocks including 3 stainless steel top plate screws. When the vibrato bridge was first designed in 1954, it had a machined steel inertia block for the simple reason it gave the instrument the required sustain and harmonic content. Over the years, manufacturers have continuously made this part more inferior in order to cut costs. We manufacture an exact replacement block for stripped original bridges and it can be retrofitted onto any reissue instrument giving a dramatic increase in both sustain and harmonic content."
