I tried installing about three different types of locking tuners from three different manufacturers on my PRS SE Custom 24 guitar, to be honest they didn't improve the tuning stability of the stock trem on my PRS SE Custom 24, it was mostly due to a combination of friction-issues in the nut slots and manufacturing flaws in the tuners, I even tried lubricating all the nut slots with both graphite from a pencil and specially made lubricants, nothing worked, hence the reason I decided to replace the stock trem with a Floyd Rose system, the only thing the locking tuners did was to speed up changing out the old strings for new ones.
