Maybe I'm missing something here, or didn't clearly state what I meant. A standard JM has a 21 fret, 25.5" scale neck. I'm looking for a 21 fret, 24.75" scale neck.
According to Warmoth, the 22nd fret on a 24.75" conversion neck sits just over the end of the heel, and would therefore leave an exposed slot where the fret was extracted. Looking at the 24.75" on my Strat, I just don't see the interference, just as Cagey suggests. Maybe the JM neck is built differently?
In any case, I'm not really concerned about trimming the fret board. I have a well appointed woodworking shop and years of experience. My problem with this whole deal, is why should I have to go through all the hassles of redoing the heel, when all Warmoth would have to do is NOT install the 22nd fret and properly trim the fretboard during construction.
I'm sure it makes good sense to them, but I just don't see it.
