Re: American Telecaster...what do i do:S
i have just bought a vintage white american series tele myself - great guitars.
In the end i opted for a maple fingerboard. I tried several examples of both. I found the maple to be brighter, a bit thinner sounding, with slightly better note separation. The rosewood was warmer and rounder. From a tonal point of view i actually slightly prefer the rosewood, but i prefer the feel and look of the maple.
As far as pickups go, do some searches. There are so many threads from the last six months about tele pickups. Personally i am going to stick with the stock ones for a while. I actually think they are quite good, though you may want something a bit thicker sounding with more output for the bridge. The common suggestions on the past threads seem to be the Jerry Donahue and Antiquity. The Donahue is apparently higher in output, more mids and less bright, so may suit your style a bit more. But I havent tried either so wont comment any further.
