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.
