"it's exactly what I hoped for"

That's Rob M. spontaneously expressing his satisfaction. His early 60's Stratocaster has benefitted with the addition of a Callaham replacement tremolo. The reason this particular modification makes sense is that many of the older Fender vintage instruments had saddle sets that spread the strings too wide over the fretboard making them easily slide off the edge during play. This particular Callaham tremolo (they have several flavors) has the same six mounting screw hole arrangement as most vintage Fenders but with slightly narrower string spacing. This means we can move the strings inboard slightly without having to cut into the wood at all, which is very appealing to anyone.

We have all kinds of ideas to make guitars better.
