Hipshot Ultralite Individual Bass Tuner with Fender-style Knob Lightweight compact tuner for smaller bass headstocks with 20:1 gear ratio. Convertible for installation on either side of the peghead. Mounting screw, washer, and hex bushing included; 9/16"-diameter peghole required. Sold individually. These tuners weigh 1.8 oz. each, compared to approx 2.3 oz. for a sealed Gotoh tuner and 3.5 oz. for a Schaller-style tuner. Pilot holes required: Installing delicate screws such as these into hard maple requires great care and accuracy. We highly recommend using a 3/32" bit for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly. Item # Weight 4241 0.1300 lbs. (0.06 kg)
