Re: Scalloping
I recently had the opportunity to play a very unique guitar... It was a Gibson Les Paul (with a nice flame maple-amber top) with EMG's and a fully scalloped fretboard. I had only played a guitar with a scalloped board once before and then didn't really get a chance to get a hang of it... but I actually got to sit down with this one and this is what I can tell you.
Scalloping offers TOTAL control over the strings. Therefore it also allows you TOTAL control to screw up

I play with a fairly light touch and it only took me a few mintues to adjust to the fact that there was no wood under my fingers. Here was my experience:
PROS-
- Vibrato and bends were waaaaay easier and allowed total freedom of movement so long as you didn't fall off the fretboard. It was pretty liquid smooth. You could even get vibrato by pushing down harder on the strings!
- Tone seemed to sustain just a little bit longer.
- Attack and percussiveness of notes were pronounced and made for a more "open" tone.
Cons-
- My only gripe was that having such total control over the strings made it seem like I'd been playing very heavy-handedly, so I had to get used to not pressing quite as hard or else the strings would slip out from under my fingers or my fingertip would fall off the string into the scallop! Also the note would go out of tune if I pressed too hard. But once I relaxed ajdusted my grip a little bit I was playing much better, as sweeps, trills, and legato techniques became easier. My energy wasn't focused on force now as much as it was on accuracy.
- Playing barre and open chords felt a little bit weird.
In a ntushell... it took a little getting used to but after adjusting my style I was able to play just as well (and possibly just a little bit better) on a scalloped board. However scalloping is not for everyone so I'd recommend you try it first.
