This bridge look super cool on my Fender Meteora, a lot better than the Fender stock bridge. But it does not only look cool, but works better. The arm is exactly as tight as I want it to be, nothing is loose, even when I set it up so the arm falls freely when I release it from my hand, when in Fender despite the fact that you have to screw the arm in there's still a lot of rattling going on and have to use some small spring to stabilise the trem arm. Fender is a lot o hustle, when with Gotoh you got premium quality hardware for even lower price. I've not noticed even a slightest trace of compromise in overall quality of Gotoh EV510T-FE-C. Tuning stability, weight, sustain, their string routing inside the trem block - I just can't help but love this bridge.
Small tip, if you do not want to screw the arm in, just unscrew the screw at the bottom of the trem arm socket. I've made a new/spare screw with the thread filled smoth so it goes inside the arm without the need of "screwing the arm in" and it still is super stable.
