Yes. A standard right hand guitar generally has its tuning machines on the left side (would need 6R Right Hand tuners), while the reverse headstock of a standard guitar would have a headstock that usually seen on a left hand guitar (tuners on the right side), so you should choose 6L Left Hand tuners.

Billy Nitzsche

Very beautiful pegs, a bit tight, and during

Zackery Kiehn

In general, the rides are good, but 2 screws broke, I had to drill a larger hole, the height of the pins themselves are not quite even.
I cannot return, because I have already pasted the response nuts on the neck, how many they are slightly less than a hole

Tanner Adams

Excellent quality bolts

Marcelle Cummerata
