i think it's funny how so many of you put so much stock into ONE guys youtube video about kahler flaws. the first time i've ever heard of these flaws on kahlers was from this video. i've mentioned this before, but i've used a kahler equipped charvel for years (with brass rollers and a kahler locking nut at that!) and have no more stability issues with it than an OFR.
alot of you mention he was also using a floyd lock nut with the kahler, maybe he didn't lock the nut down tight enough? he never mentioned anything about setup and adjustments on the kahler either. i'll believe a review when i see someone post a video of an ENTIRE setup AND demonstration of whatever trem is being reviewed.
now, on topic
, i just got to try a 6 string ZR. it was definitely a solid trem, but i HATED the feel of it. very stiff. i'll take the kahler.
