1 lx 3 months ago No Affiliation With Sellers.I just noticed this '51 Electro re-neck: Gretsch not only did a reneck with the heel dowel/neck lock, it appears they also installed an adjustable truss rod; the Electros didn't gain those until '54-55 when they were in their Corvette iteration. Interesting that Gretsch went to the trouble to do that. EDIT: Just looked at the neck heel again, this is a whole new (post-'57) neck. I don't think the tuners are original. On this Synchro 300, Gretsch just chucked out the assymetrical non-pressure neck and installed what appears to be something like a Country Club neck. (I suspect this is also the case with that stupidly priced Synchro 300 with the Falcon neck that bevete keeps hawking.)I did try an acoustic Falconized Synchro 300 a few years back which played and sounded fantastic. The seller thought it might be a factory re-neck. There was a detail on the construction which was not factory despite the "d" shaped neck and neo-markers - the headstock face tucked under the nut. You only find that on Modern Gretsches.
