I knew of Warmoth back in the '80s when I was a teen and saw their ads in cheesy guitar magazines. I was too chicken (and cheap) to build anything until recently. Now I'm hooked, there's a bunch of VIPs with F holes in the "in stock" that appeared recently, I'm scrambling right now to snag one.
There isnt anywhere you can go to sample all the options. Sure, you can go to a Guitar Center and play a bunch of different guitars to sample neck shapes and pickup tones. But honestly, it isnt the same. You have to take a leap of faith and start building. Do research, and be honest with yourself and what your needs are. Once you've spent $500 to $1000 on parts, finish it, put it together, and start playing it, theres no, or very little, going back.
The only place you can go to test and sample anything is online, their website, this forum, youtube clips of Warmoth builds, the Warmoth flickr group, etc. But, of course, theres no substitute for a hands-on experience. But if you proceed with caution and self-control, you should end up with a killer ax. I know I did.
Below is my first build, sort of, the only Warmoth part is the Body, Bubinga topped Mahogany Thinline Body. two F holes and recessed tune-o-matic. Karosa made the neck, Goncalo Alves with Rosewood board. Pickups are by Reed James Custom, P90s with solid exotic Cocobolo wood covers.
