Gotoh SG381 H.A.P L2+R4 Non-Locking - Black

For sale are the stock Gotoh H.A.P (Height Adjustable Posts) Non-Locking tuners from my Caparison TAT Special. I am swapping them out for Gotoh Magnum Locking tuners. Please make note that these are a set of L2+R4. Below are official descriptions of these tuners:

Gotoh SG381 HAP L2+R4 Adjustable Tuners Set w/ SMALL Buttons - BLACK

With the H.A.P system, it's ability to adjust post height, means that the pressure which the nut puts on the string can be adjusted on each individual string, so obtaining the ideal amount of string oscillation. This ability to control string sustain and touch tension allows the musician to configure a set-up which perfectly for them. Thanks to its ability to set the post at a lower position compared to a standard post, H.A.P is particularly suited to straight neck type instruments, which have only a slight head angle.
