Has Fender/Squier ever released a Jazzmaster with ...

[kgbAttack]

Squire also did a set neck, thinline, double humbucker tele in 24.75 in their master series. I had a natural one. I was in love with the look, but I never quite got on with it.

My friend has one that is double-cut, thin line, set neck with P90s and TOM bridge. Essentially only vaguely a tele, but it’s cool. Not sure about neck scale though.

Almost certainly not what you had in mind with your question so I’m only really posting for novelty value but ...

It does say Fender and Jazzmaster on the headstock*

* for people from future civilisations, if you’re reading this and the link is dead, it’s a Fender Japan Champ Jazzmaster with built in speaker.

I can’t imagine actually desiring that squishy slop of a shorter scale.

You mean the standard scale of Gibson, one of the most popular brands of electric guitar?

Ok then...

Yes, precisely that.

Oh, I'm building one just this very minute. In fact, the only reason I'm here is that I'm goofing off from filing the frets.

The body is from an Affinity Jazzmaster I bought in a store brand new just to do this. The neck is from a (mumble,mumble). It doesn't take much to make it work, just shave maybe 3-4mm off the butt end of the neck. But I haven't assembled it yet, so I might have to modify my calculations if reality intervenes.

The thing is I love love love Jazzmasters with all the"features" removed, and I really prefer the sound of the Gibson scale.
