Now, THIS is what I've been waiting for for about the past twenty-five years: The Wilkinson Vintage Strat Vibrato with pop-in arm. (With a steel block, no less!) I love vintage-style Strat trems, but I get tired of the arms becoming wobbly. I've tried the old plumber's tape trick, the small-spring-in-the-hole trick, and many other tricks, but they're all short-term fixes. Now, you can insert the arm into a Delrin® collar (complete with adjustable arm tension) to get rid of temperamental vibrato arms. I've order three of these vibratos, and I'm looking forward to installing them in two of my Strats and my "0le FUZZY" custom Tele, and heartily using them, a la Jeff Beck, Jimi, Hank Marvin, etc. Nothing more to say, really, other than Trev Wilkinson--God bless him--always creates a better mousetrap.
