Hipshot Licensed Ultralite 1/2" tuners for sale. These fit a 4+1 headstock, I removed them from my NYC Satin Sadowsky bass. 16mm hole required, these are NOT the USA version. $65 shipped CONUS, Paypal OK. FULL DISCLOSURE - the treble side tuner key was loose when I recently removed a set of flats. I tried to gently loosen the hex screw (you need to do that to break the sealer they use on the screw), and then tighten it - I could feel the head wanting to strip. Once I removed the tuner I was able to tighten the hex screw going really slowly and carefully, but I wanted it to be known in case further adjustments were needed. You may be able to get a replacement hex screw from Best Bass Gear or take one off a similar tuner if so desired.
