I've owned four of them. Fabulous guitars. The neck profile is a "C" shape - thinner than standard strats, but still nowhere as thin as a wizard or wizard II profile.
The YJM is the only model offered by FMIC with Dunlop Super-Jumbo #6000 frets. These are basically bass guitar frets on a scalloped one-piece maple neck (or rosewood slab)
The 42mm nut is solid brass and the pickups are DiMarzio stacked humbuckers.
The body is two-piece alder with an offsett seam - this is the only strat that is not a Custom Shop model to have this feature - very expensive to manufacture.
I've had over 20 Strats from $200.00 MIM's to $4,000.00 Custom Shop models and all 4 of my YJM's were among the top strats in the collection for playability,weight and tone.
