Re: Custom Building a tele
I've built about 6 guitars, including 3 Teles, and they are my main gigging guitars...I love being able to build them just the way I want, and people's reactions when they ask what kind of guitar I'm playing and I tell them I built it! Which parts specifically are you looking for...neck/body, or hardware? There are a lot of options, and it depends what you want. For hardware, check out
http://www.callahamguitars.com/ or
http://www.glendaleguitars.com/ Neither are particularly cheap, but you get what you pay for! I have built guitars with Callaham parts, which are top notch...they make heavier bridges. Haven't used Glendale stuff yet, but they have a lot of options and tend toward a more vintage, light-weight vibe. Also, if you happen to be going vintage style, I suggest Kluson-style tuners...they make locking ones that fit in the Kluson holes and look pretty much totally vintage.
I have built guitars with alder and swamp ash, and I will say that for me, the biggest, most tedious pain about the entire experience of electric guitar building is doing the grain fill on a swamp ash body. The grain filler is like tar, and very messy (do it outside and wear old clothes!). But, the end result under a translucent finish looks amazing (think of all the classic Teles). Here are pics of a swamp ash-body baritone Strat I built, and a swamp ash Tele body with grain filler and clear coats (trying to decide what color I want to make it). Even though grain filling is a pain, you only have to do it once, and to me it's totally worth it. And honestly, all of the classic Teles have swamp ash bodies...get a lighter weight one if you can, they resonate wonderfully!

Let me know if you have any other questions...oh, and one other thing...if you're going vintage (and it's totally fine if you're not!), you gotta go with 21 frets...
