If you are building a Guitar, I suggest you use Warmoth parts.
I know, they are expensive. But I had good experience with mine,
and that was back in 2009
and the instrument is still excellent and has given great service all
this time.
This thread petered out a few months ago, so I'm curious about whether your tricked out neck
was usable, or if you returned it, or what.
My Warmoth build:




I built this bass in like 2009, not knowing if I could master a fretless neck or not.
But it was my dream bass. Funny, I bought the least expensive body and neck
I could. And it still was a lot. But after I did master the fretless technique, I didn't
need my fretted basses any more, and sold them in 2019 (with so much other stuff).
And I'm sure I've made hundreds of dollars playing this bass since 2009.
So she's surely paid her way. I wouldn't trade this instrument for anything.
I named her Luretta after a song by Townes Van Zandt.
