Geoff has been working on an interesting project today: scalloping the fretboard on a Yamaha Silent Guitar. This allows for extreme bending and vibrato techniques, without that pesky fretboard getting in the way – kind of like a sitar, which is where the idea comes from. Scalloped fingerboards have been popularized by John McLaughlin, Steve Vai, and of course Yngwie Malmsteen.
