I finally got mine installed and set up, took some time to get it all fine tuned but no loss in tone as far as I can tell.
I used a tremolo stopper on mine, nothing fancy, just a plain L shaped piece of brass that mounts inside the tremolo spring cavity.
It was frustrating to say the least, my strings were not new but they wasn't old either, basically put on and hardly played.
Keeping it in tune seemed to be off the list so to say, but once I got it all nailed down and adjusted it stays in tune and changing from E to D is much quicker now.
This is the first time I've installed one of these and it wasn't easy, I think if I did it to one of my other guitars it would be easier now, which I"m contemplating doing one or 2 more.
Now if I could find someone to route my Epiphone Les Paul for a Floyd that would be great. Not willing to attempt that one.
