I owned a brand new JS1000, but I kept going back to My RG570 (Wizard II) and RGR570 (Reverse headstocked SuperWizard). The neck feel on a JS
is very different than general RG based guitars:
-The Multiradius neck (not Compound fretboard, you don't get that on production JS
's) is thicker in the lower register and flatter in the high register.
-The radius of the freatboard is a lot smaller on JS
(250mm) compared to RG (400-430mm), resulting in a much rounder freatboard on the JS
and a much flatter one on the RG's/Jems.
I just couldn't get used to the neck of the JS
, wich is much more like a fender strat. I felt like my hand was backed to fit an RG neck. I just got a JEM7DBK in stead (still have to post pics). This one has a unique neck among JEMS, it's alot like a SuperWizard, wich means it is flatter and more D shaped in stead of C shaped compared to the Wizard II.
Genreally due to this smaller fretboard radius on a js
, you can't get action as low as on a flatter freatboard radius because choking of bent string will kick in faster.
As for the pickups, the Fred has considerable less output than a breed and certainly an evolution.
So sound in combination with neck-feel, you might be in for a real surprise when you buy a JS1200 (at least I was). so my advice since you own an RG now : don't buy a JS
before you've played one !
