My fantastic Fenix by young Chang strat came with a licensed Floyd that was a bit loose and kept getting out of tune when using the trem bar.
I was a bit scared to do the change but it went smoothly. I did watched a couple of video tutorials though.. In the end, the trem is way better and the tuning is more stable.
Funnily, I bought this guitar 2nd hand for 35€, this trem is almost ten times the price of the guitar… Admittedly, I bought it fairly cheap ;-)
Great upgrade, no regrets
