Here's a brief history of Jake's guitar from what I've gathered.
This started out as a sunburst 1974 Fender Hardtail Strat, which Jake's friend at the time who worked for Charvel guitars customized it.
His friend painted it white, with a matching headstock who's profile was sanded down from the large 70's CBS shape to the current Charvel / 50's & 60's shape. A 'Charvel' logo was also slapped on by his buddy.
The now 'Charvel' was fitted with a Seymour Duncan JB humbucker in the bridge, and 2 DiMarzio SDS (DP-111) single coils in the neck and middle positions. They were also reverse slanted ala Strat bridge pickup.
I'm guessing for better low end?
Anyway upon further research I found some pictures of another White guitar, which I believe is an actual Charvel. The picture was from around the 'Ultimate Sin' tour which was 1985/86.
At that time he may have had an endorsement through Jackson/Charvel.
I'm not too sure about that though.
Here's the other White Charvel:

As you can see it has a Strat style trem on it, which was probably blocked because Jake didn't use a trem during that time period.
It also has a single Humbucker, which was most likely a Seymour Duncan JB.
The headstock was bare wood, with a Black Charvel logo.
Well at this point I had a full pallette of options in which to choose from.
There are things from both guitars that I like, so I decided to take the 2 and make one that will suit my own tastes, yet still come off as a tribute type guitar.
Here's my parts list:
Body - Eden Lefty Strat Vintage White
Neck - Charvel Model 1 (matching headstock color & blk. Charvel logo)
