If you're going custom why not use a true single coil pickup mounted right next to the Sustainiac?
because.......ugh............I'm a visual thinker with a very strong sense of aesthetics, and its going to be a tele-based guitar.....and it'd be a covered nailbomb bridge, as a chrome covers look kewl, and ugh I don't think it'd look nice with something that look like an uncovered humbucker in the neck, and the thought of middle 3rd pickup on anything tele looks atroicous.
ok, just shoot me.
2nd, body would probably be alder, as from what I understand its really solid, certainly more dent-resistant than basswood, and just gives a decent all around tone. I can't afford multiple guitars for different styles so it'd would have to be like my ideal lady, all you need is one.
From what I've seen I'm really itching to go Legra, I just feel like getting more specs down before bothering Mr. Bob Johson.
