I do question the validity of locking tuners on a fixed bridge guitar, to myself that is.
I can’t quantify saving a few seconds per string, making a couple of winds around the tuner.
Sad as I maybe, I actually find string changes therapeutic. Having never smoked, I imagine it’s like rolling a cigarette (Caribbean or otherwise). The whole process being part of the experience.
Heck, whatever anyone else wants to do is fine, because it’s their guitar.
