So I've been playing a baseball bat U-shape neck (TRO-FAT) on one of my jazz teles for a year or two and up and decided it's too big for me the other night. Too fat and frets too big (though I can deal with the latter). I much prefer the TRO-V on my home built Jazzbo Hepcaster tele. Still 1", but V-shape and with vintage frets and a 7.25" radius (not that I mind 9.25" or even 10"...I've had both). But at least for jazz, I like this better. I've also been playing 12s on that guitar and they just seem a little much. I think my jazzbo got mistakenly set up with 11s when they cut the nut (only just realized that too) and I find them much more comfortable to play. I can play the 12s but have to tune down a whole step for them to be comfortable. I can use pedals to thicken the tone if necessary so not a dealbreaker. I also have a tele with a 1" C shape I like and another with a 50s Baja (V-shape) I like pretty well. If I were having one custom built by, say, Musikraft, I would probably do Soft V or chunky C (maybe .85" - .9" at first fret) 1-11/16" nut 9.25" radius (unless for jazz, then 7.25") Vintage frets (6230...and probably stainless) Heel-adjust truss rod (prefer these universally...I find they are easier to adjust...less likely to strip out than an Allen nut...and have a better weight distribution than headstock-heavy ones with the adjustment at the headstock) What about you guys? What are your favorite neck specs for your ideal neck?
