Re: Who's done a Warmoth?!?
My first project guitar was a Warmoth franken-strat:
I had them finish it and was really happy with it at first. Both the body & neck were off the "Thrift Shop" (now called the "Showcase"). The quilt is pretty darn good IMHO, and the neck is quartersawn maple. (BTW the bridge pickup is "right side up" now for whoever noticed it before.)
While MikeRocker is right about ReRanch being a great resource for DIY finishing, I have been working on my second project FOREVER because finishing is a bear if you are a perfectionist like me and have no experience. If you can, I'd recommend having someone else finish the first project so you can learn everything else, then take on the finishing aspect of building a guitar.
Warmoth does offer the greatest variety of body shapes, and their wood is generally very good. However, I got frustrated on my second project by Warmoth's policy of applying an "upcharge" every time you move an inch away from the basic menu. I didn't understand why they couldn't make a 10-16" compound radius neck with 21 frets. They just said "No."
That's when I looked around for alternatives and discovered
USA Custom Guitars. Tommy Rosamond is simply a great guy who never says "No". He and several of his employees are Warmoth veterans, and they all are guitar players. That makes a big difference when you're asking for advice, picking out wood, etc. (Not knocking "Bill" at Warmoth - he's a great guy too, but some of the guys there don't know anything about guitar construction as far as I can tell.)
Then there's the "Warmoth construction" neck. I'll ask forgiveness from y'all who've read this before...
I unintentionally did an A/B comparison of a Fender neck and the Warmoth neck on my MIM Strat because I wanted the back contour, compound radius, and bigger frets on the MIM body. What I discovered was that the Warmoth neck sucked the highs & chime out of the guitar compared to the Fender neck. The double expanding truss rod is a lot of metal in your neck, and Warmoth routes a big, deep channel under the fingerboard for it. Also, the fingerboard is extra thick - not a problem with maple, but not great with rosewood or some other wood that's supposed to be "warm". I expected the Warmoth neck to sound better and ended up deciding never to use a "Warmoth construction" neck again. The "Vintage" and "Vintage/modern" construction necks from Warmoth are fine as far as I know, but the options are more limited there. In fact, I've got an unfinished USACG neck waiting for some attention to go on that Warmoth body.
Sorry about the long post - I have at least as much fun building guitars as I do playing them. (I'm better at building and wiring than playing anyway... )
Go for it and have fun
