Vintage Bolt-on Fender Acoustics?

[Steadyriot.]

That's awesome! My only suspicion there is that the Shenandoah is more expensive/harder to find due to that fact too though...

Just looking at that it seems that the neck goes way further into the body than a standard Fender neck though, so I'd assume that it has the neck mounting screws in a different place.

You're correct. The flat end on the back of the heel where it's bolted onto the body is pretty long. You would have to dowel the old holes and drill new ones.

Will once converted a few acoustic XII necks.
