Gentlemen, Kahler, if that is what you are referring to, is a surface springmounted trem. I didn't even know they still made Kahler, but amen if they do. Best tremolo, imho, ever made. I always idolized Eddie Van Halen and he endorsed Floyd Rose, but I played a Kahler once and thought it wasn't a Floyd. Then I realized it wasn't a Floyd I wanted. I fitted my '82 Stratocaster with a Kahler (long since sold), my Charvel model 3 with a Kahler, a guitar I designed with a Kahler, and finally my Jackson Custom Soloist (I believe it is '88) with a Kahler. Of course the Jackson being a CUSTOM Soloist back in the day, came with whatever you wanted on it for around $1700. I have a white Kahler with the flip up nut locks on a custom purple body with my name in ghost letters...had a friend design the lettering and sent a sample in for the color. Man how I miss those days of Jackson-Charvel.
I think Fender runs the show now, right?
