Lesson learned, and I am posted to warn anybody else to be careful. I ruined both my mikes today. Totally f#$%% up. Ok here is the deal, I always thought they ran nice but had no pulling power so I though why not add some snot to the drivers. It seemed reasonable, Well I followed the directions on both and applied the best I could. Evidently it was uneven. When it cured I tried both and the wobbled and shimmed all over the place. Well supposedly with an exacto knife you can remove the snot. So that is what I did, and of course the wheels got turned out of quarter. So I had to remove the bottom plate which is a pressure fit. Well on the one I removed and quartered and the plate would not snap back on, you got it if you remove the bottom plate is is so close you might just rub the tab that holds it in place off. On the other the plate snapped on but I didn't quarter it quite right so it runs like junk. I might take the plate off but my fear it will probably just wear off like the other. The plate on the mike is a bad design, not held by screws so that troubles me, and the snot well, it is a crap shoot to apply the stuff right on such a small scale. Lesson learned. Done. Be warned 400 buck down the shoot. Upset? understatement.
