Just about to fit some Schaller locking tuners to my PRS SE Singlecut. When stringing do you first, loosen the screw at the back, tune up to pitch and then lock the thumb screw at back ?

And also, should there be minimum wraps around the string post ?

On my sperzels you just pull the string through so its kind of tight, lock it, tune it

it cuts down on having to turn the knob over and over and over like on regular tuners.

and i think your supposed to crease them inward, idk i ahvnt switched my strings in a while. There are videos on youtube
