My Juzek has an Eb neck. And before that, my ply had an Eb neck. I have a La Scala on order and it has a D neck. I know there is going to be some adjustment, but I figure that I can get a feel for it by running scales, arps, and excerpts for a few weeks. One thing that I am wondering, though... Say you're playing an F# major scale, do you finger the F# (below the octave G) with the 3rd or 4th finger on a D neck? Normally, on my Juzek, I would finger it 2-4. Does the 1/2 difference in the neck joint change the fingering? Everything else should lay out pretty much the same.
