Hi Tommy, the action is sweet. I had the guitar set up by a luthier here in Columbus. He's the real deal so that guitar plays great. I can snap a few photos (of the action) and share them w/ you if you'd like. I can have them to you by tomorrow, just say the word. Thanks!
Sorry I didn't see your message earlier, hope it's not too late :/
If you've got a vice big enough, use it! You can always put a smaller piece of wood in between if you need to press on a small spot to correct something afterwards if necessary.
Good luck, hope I could help
I'm not sure on that one, I've never used a single coil in the bridge position on any guitar let alone a low-tuned monster. I was leaning toward the TW myself but just didn't feel like spending the extra cash. I suppose you could always orient the pickup so that in single-coil mode the active coil would be the one further away from the bridge if necessary.
I think it worked out perfectly. In hindsight I should have kept it that way on the second build. This summer I'll probably be doing a fanned fret version which should help the tone even more, though I'm thinking of having fewer strings since my playing is still not making much use of the 9 yet.
As long as all of the frets are level, including the zero fret, you'd be good to go. If you were going to make a zero fret out of something else brass might be too soft. Brass makes a fine nut because the string will never rub back and forth at all but a zero fret needs to take a bit of abuse. You could just make a brass nut with very shallow slots and add a secondary string retainer to keep everything in line.
