Re: JS1600 retrofitting tuners?
It's been quite a while since I've been here but I noticed my last post. Thought I'd provide an update for any other JS1600 owners who might be having tuning issues. After my experience, I can't imagine someone NOT having problems with theirs if you do any degree string bending.
In a nutshell, a set of Schaller locking tuners retrofitted perfectly, with zero modifications needed. Beyond that, I removed the garbage retainer bar all together and paid to have the nut professionally replaced by a top notch luthier after the techs at Hoshino USA couldn't quite get it right after TWO tries. The guitar stays in tune perfectly now and is one hell of a player. Overall, my conclusion is that the use of a retainer bar just does not work well on this guitar. A well slotted nut and string trees would have been a far better design. Regardless of the retainer bar height or smoothness, there is still far too much of a break angle for the strings to move freely enough with the original design. The only way around this is to remove the retainer bar from the equation.
