Here's a question no doubt has been asked ten thousand times already but what the hell... I've searched and haven't found it yet on the msg board. One of the elders will have to clue me in..
If Vai's original specs for the Jems was to have fret 21-24 scalloped, why don't all models have that feature? The Jem10 and Jem90, for instance, etc..
The VWH has always had scallops afaik, so that's probably why he still uses em
