Two sets, new, 3L + 3R tuners with Height Adjustable Posts. 16:1 ratio, small chrome buttons. Bought for a 12-string with a thicker headstock but not used. I believe these are often used on electric guitars. Photo shows post lowered and raised. These are much more expensive in the US, hard to find in Canada except by special order, plus international shipping. Asking $60 a set.
