That's what I though, but it was the same for both sets I had. I may have had a couple of rouge sets or they may have been from a Friday afternoon batch, but they were two different guages. On the other hand maybe they forgot that fender made mustangs, musicmasters and broncos and designed the strings for 2x2 headstocks like hofners & danelectros.
I suspect that the 32" TI jazz flats may fit - I've just put a set on a daisyrock, bit forgot to measure them up against the musicmaster. The Rotos short scale flats definitely fit,but the last few sets I bought had a very inconsistant feel across the strings where two were smooth one was a bit rough and one was very rough. They sound nice on my '71 music master though.
Have you thought about what pickup you're going to use in the musicmaster when you put it back together? I can recommend a plain black covered cool rails strat humbucker from brandoni - It was £30 when I got mine. When fitted it looks 100% identical to the original pickup. Wire the coils in series and it sounds massive. Also of course there's none of the hum like the original single coil pickup and the bass doesn't sound weak & wooly at all which was a problem particularly on the E string with the original.
