I bought this Schaller to upgrade a Floyd Rose 1000 series. It is superior to that unit because it keeps tune better, it feels more heavy, more solid and all the moving bits move more fluidly. The execution is more refined and I found no flaws. I bought the 42 block version, which did not fit my guitar but I didn't use it anyway, as I replaced it with a 32 brass block. The sound is amazing.
One thing that I must point out: in these pictures, you can see the Schaller logo, but my unit is imprinted with Lockmeister instead of Schaller. I looked on Schaller website and indeed they use the workd Lockmeister as logo. So these pictures on Thomann are probably for the older version.
Other than that, it's an awesome upgrade and, compared to my original Floyd Rose, it feels the same. I will probably upgrade all FR1000 with this in the future.
I recommend!
