Jaguar 24" neck on a DuoSonic body?

[helvetg]

I've read around that the two are interchangeable, even though the DuoSonic is a 22.5" scale, can anyone confirm this?

I'm not sure how the two can be interchangeable if they are different scale lengths, but who knows, the guitar world works in mysterious ways

Can confirm, but can't explain exactly how it works.

Fender Made Mustangs and Duos and Musicmasters where the necks could be ordered in either 22.5" or 24" scale.

The necks may physically bolt up one in place of the other but that doesn't mean it will work, necessarily. If the Duo-Sonic nut is 1.5" closer to its heel than the nut on a Jag neck then yeah, it's a legit swap because that will yield the proper distance between the existing bridge and the nut of either neck. I guess you need to have them in front of you to determine if that's the case.

Or to establish if the heel-to-nut lengths are in fact different on the two necks remotely you could use Stewmac's fret distance calculator or something to figure out the actual distances between the frets on these two scale lengths and just count the frets you see on the necks, which should work well enough to reveal a 1.5" discrepancy if one exists. And actually, a simple fret count should be enough. If they have a similar number of frets, one will have to be shorter than the other and your swap should be able to proceed.

If they could in fact be ordered with either scale length, it stands to reason that the neck length was the element that was altered. It wouldn't have been the heel pocket or bridge placement.

No need to guess. The 24" mustang and duo sonic necks are identical specs to Jag necks. The 22.5" necks are "conversion" necks that bolt at the same location. No difference in the bodies between 22.5 and 24" models.

I thought it was because of the long bridge screws?

It's because the 22.5" neck is what they call a "conversion neck". It's designed to work on the same body but change the scale length (just like how Warmoth has a 24.75" conversion neck for strats/teles/JMs). It's basically just the same neck with 1 less fret, so that the locations of all the other frets are in the same spot...in other words, like putting a capo on the 1st fret of the 24" neck, except building them to be that way permanently.

Hope that explanation makes sense.

No difference in the bodies between 22.5 and 24" models.

That is 95% true.

I have seen a super small percentage of 22.5" scale mustangs that actually have a wider bridge.

Fair enough. I just meant in terms of neck compatability with the scale lengths.
