Hi curtisa, that would also be my suspicion. I can't wait to hear how it sounds when it is actually working (and I have resolved the intonation problem).

Bingo curtisa! I think you've hit the nail on the head. This Floyd Rose bridge is not original. I blew up the picture from the reverb ad you pointed me to and the factory bridge is radically different. In fact you can see that the saddle takeoff points are closer to the nut than in a Floyd Rose. So I'm gonna deepen the knife edge slots. Awesome detective work, thanks!

Thanks curtisa! Yeah I don't think it's working right. For example the tone pot works as a volume pot. And one of the miniswitches (the one for the humbucker presumably) is a 3-way (the other two are 2-way). Maybe the humbucker switch is double coil/single coil/off and the other two are on/off for the single coils. Time for some reverse engineering!

I am working on a 1985 Tokai Super Edition JSX70. Does anyone know how this thing is wired, what the switches do, etc? I can't seem to find any info on the web. Thanks for reading.

I am working on a 1985 Tokai JSX 70 with a Floyd Rose. It will not intonate, in that the bridge saddles are as close to the nut as they can go, yet it is still flat when the fretted at the 12th fret. All the little bridge shoes are pushed as far towards the nut as possible. (To double check, I pushed them as far away from the nut as possible, and it made the problem worse.) There is no excessive wear anywhere on the bridge. The pivot mounting bolts are straight. The nut is in the correct place. The neck is in the correct place, in the sense that the mounting screw holes are not worn, they line up, and the neck is fully seated in the neck pocket and cannot go any further towards the bridge. The bridge plate is level with the surface of the guitar, about 2mm high. This is an old guitar and it is a mystery to me how it could have gone through 37 years like this, but there it is. It seems to me that the best fix for this is to grind the knife edge slots deeper so that the whole bridge can move closer to the nut, reshape the knife edge, and then fine tune intonate with the little bridge shoes. Does this make sense, or does anyone have a better idea? Thanks for reading.
