There's plenty of specs on the jemsite.com mainpage, but as you probably know they come with those Breed pickups in the green/black/orange variety. Along with matching single coil and funny colored plastic knobs and selector switch. Didn't dig that.
So this guy got Duncan JB/Jazz pickups, fender 5-way multipole switch and metal dome knobs in cosmo powder (think that's the color) which matches the rest of the hardware. Think the knobs are from an RG3120? The only other thing I did was sand the finish off the neck. I refuse to play a guitar any other way(pic 12 you can see the neck is a bit dirty).
I got this guy new from the store I always go to. Real tiny family shop I worked at for a bit. They really had to fight to get on the list and none of us could believe when we checked the order status and Hoshino had most definitely given them one. They were so excited they asked me if they could put it on display for a week or so after it arrived. I was the first person to see it, they called me when they had a box in their shop.
I'll admit, I barely played this guitar over the last year or two. I totally got burnt out on the trem business. The Tremol-No has been a savior for me. The pickups were a huge help as well. I had forgotten how perfect the nut width is and how surprisingly comfortable the radius on the fingerboard is. I even like the skinny neck now, the guitars I normally play are considerably fatter. I even find myself "unlocking" the trem now and then. I've had a real rebirth with playing this thing, which is why I'm suddenly so excited to post about it.
It's weird, as I was getting more and more into strats, I thought that the 7VWH had the best neck profile for a JEM. I hated how thin the new ones were. Now I kind of realized that the strat necks are perfect for strats. I love those fat and short necks. But on this type of a guitar, the new neck profile is really great. It's just so comfortable and easy to play. It seems to fit like a glove.
