Thank you very much, guys!
Walter,
I wanted to buy a Rockinger baritone neck too, but when trying out some cheap donor guitars, I preferred the Stagg over a Squier. When I took it apart, I noticed that the neck pocket was not Fender-compatible, so the Rockinger neck wouldn't fit either. Then I decided to do it the hard way, and build the neck from scratch. I learned a lot along the way, with trial and error, it took me a long time, lots of sweat, swearing and cursing.
Coyote,
I put on a d'Addario medium baritone set (XL157) .014 / .018 / .026 / .044 / .056 / .068
BluesOwl,
I will report back in a few days/weeks. The strings are balanced very good, better than my Gretsch "jet baritone" which is essentially a 6 string bass with all wound strings tuned one octave below standard tuning. I'm still wondering myself wether this one is a beauty or a beast. Actually, I like them having both sides
