I bought this tremolo arm to replace the one on a Floyd Rose 1000.
Having a guitar with a Gototh 1996T and loving the push-in arm, I went with this.
Great choice! The quality is what one would expect from Floyd Rose (and Schaller), while the FR 1000 arm deteriorates fast and needs to be screwed in tighter and tighter, this is durable. The feeling during use is also way better.
Also, it can be set to be "rigid", i.e. stay in place when you drop the arm, or "loose", so that it falls down when you drop it it. With the original arm, one needs to actually tighten it quite a bit in order to have a reliable response after little use.
This is a very nice product, wholeheartedly recommended.
By the way, if you have a Floyd Rose 1000 or Special and are not too satisfied with how the arm/bridge reacts and feels, changing the tremolo arm is the best cheap mod available, both the push-in and screw-in are great and really improve the bridge operation. I have three FR 1000, all have a modified arm (Floyd Rose and Schaller, push-in and screw-in) and am super happy with them.
