I like those. I hate my strat bridges with their sharp little grub screws sticking out the top....always pissed me off. You pay that much for a Strat and you get a crappy bridge? Sheesh
Go for a Callaham and you'll never fail!
I've been considering a block, bridge plate and arm for one of my Strats from them for my '57 RI, but I'll still use the original saddles.
This can be a big improvement, also mixing Callaham and Fender or Gotoh parts.
The plate and the virtual pop-in tremolo arm are the biggest part of that improvement.
I have been using Callaham products for a few years and would never go back.
They're a little expensive, I know....but quality is very high.
Now I'm curious to test those Highwood saddles...
