Are those top-load Kahler tremolo bridges still being made? Still by APM? I have one on a modified Jackson Fusion EX guitar from the 90s, and I clearly remember the time when Kahler trems appeared on virtually every guitar mag I read in the 80s (and there were lots... sigh!), an all of a sudden I have not seen one in years, except for the one in my guitar. What ever happened to all the fun in the world? (No, wait, that?s a quote for something else... )
