I intend to replace the bridge and zinc block in my MIJ Fender '62 RI strat (which I love) with something new. I'm considering either Callaham trem assembly or DeTemple titanium ones. The latter is almost three times the price of the former. 1. Which is better for tonal improvements, and is the contrast between the two huge? Is the titanium really worth that kind of price? 2. I'm undecided on changing the stock saddles because I like the stamped Fender logo for aesthetic reason. Will the Callaham or DeTemple saddles make a marked improvement in sound quality? Thanks.
