Supply88's new tuning tip is a game-changer. The world's lightest tuning lever just got 10% lighter by dropping half an ounce: Our goal was to offer a Kestrel that weighs only 4.5 ounces, but with the clearance of a full length (40mm) tip, and that is now a reality. The K240 tip is hardened tool steel with a black oxide finish, size #2 with male M10x1 threading.

We can make key dip blocks to any dip specification and any balance length. We did this 3/8” block for Wurlitzer electric pianos, which have very short keys, requiring a larger taper angle.

Anyone need a SAT IV with a new set of batteries? We have a friend who recently had to stop tuning, and has some bills to cover, so we're trying to help find him a buyer since he's not really on social media. We installed new Li-ion rechargeable batteries in this unit for him last November, so we know it's good to go. (Didn't have a photo of the actual unit, but it's blue and looks like this one I found on a Reverb listing.)
