So. took my guitar in to have a minor set up done it.

Guitar tech find it’s generally in good shape but, some of the knobs on the tuning machines are cracked. No big deal really, they still work.

The guitar comes stock stock with Ping locking tuners.

He proceeds to tell me that locking tuners are actually intended for guitars with tremolo a style tailpiece. A Bigsby tailpiece I guess?

The reason being, a locking tuner has a shorter post consequently there are fewer wraps around the post. Thus, when using the tremolo the strings aren’t being tightened around the post causing the guitar to go out of tune.

it sounded reasonable to me. But since I know very little about tuners you could tell me anything and it might sound reasonable.

is what he said true?
