ok guys, as you may have read before i sent my s470 in for repair last week
whoever the tech was, he did an excellent job.
they cut and drilled for the new 2.0 zr tremolo to fit in, and it is 10x better.
since i now have the guitar back i am now 100% sure that version 2.0 has an upgraded spring tensioner assembly on the back of the guitar, and the trem arm is also different. now the locking cap works and the trem arm just feel like butter when screwing it in, and the locking cap tightens the trem little by little for the best feel.
this is way better, and if your 1.0 zr trem breaks, send the sucker in for repair because 2.0 is waaaay better
they even replaced 2 screws i was missing and changed the plate on the back for the new version so it matches
only bad thing about the whole situation....they put on 8's...yowza, so im on my way to the music store to pick up some ernie 9's to slap on here
ill post pics if anyone wants
