That's just it, i sort of don't have an option readily available. I've been looking for a js neck forever now. And i found one, but it's a 100 Korean made. The neck is $190 shipped, frets look essentially new.
I can buy an entire js100 Indonesian version with no pickups for $230 and it's in great shape. I have a js100 body but it's in rough shape. I was going to refurbish it with a custom color... and a gotoh floyd.
I own a 540R that has a 540s neck on it. I am not a fan of the 17" radius on the S neck... but it is a fujigen neck, and i can only assume the quality is going to be noticeably less on the js100 neck. I own a js24p and love it. But again, thats a semi high end instrument. So i am hesitant to buy.
