All I can say about this product is WOW! What an incredible difference in tone from the original bridge. Callaham bridge parts are all machined by hand in-house and are made from quality cold rolled steel and other alloys that truly enhance the tone and vibration transfer from the strings to the guitar. The quality is quite apparent when handling the trem itself. All the screws fit snugly and thread in effortlessly... it is easy to tell the metal and machining is of higher quality than the standard Fender fare (even all the screws supplied with the bridge kit are made of hardened steel with heads that are much less likely to strip out; which, by today's standards, is quite rare and wonderful!).

A big problem with Malmsteen Strats (and many other Fender Start models) is the wide string spacing of the vintage tremolo combined with overly dressed fret ends. The low and high E strings tend to slip off the edge of the neck when playing. Very annoying! Well, I solved this by ordering the Callaham replacement bridges with vintage 2 7/32" (56mm) mount spacing but with the narrow 2 1/16" string spacing (normally found on modern, two-point Fender trems). This helped bring the E strings back from the edge... the guitar now plays like normal with zero slippage! I couldn't be happier with the result.
I cannot say enough good things about this product. I bought two of these and I will soon be converting my Vintage White Malmsteen over to the Callaham. I have also learned of a cool kit that Callaham makes to convert two point modern Strat trems over to the vintage six-point style. I will definitely be converting my '04 Deluxe Strat to a Callaham vintage Strat trem as soon as my funds allow! :)
I give these bridges my highest rating!!!
