[Unused] Ukulele Saddle Bridge, Cow Bone, Set of 4 at This Price! These are the ones I didn't use from a set I purchased. I will wrap them in cushioning material and ship them via Yu-Packet Post Mini (with tracking), so it will be sent by surface mail. Please allow some extra time for delivery. Thank you for your understanding. Sizes (Straight Type) Width: 53mm, Height: 7mm, Thickness: 3mm Sizes (Trapezoid Type) Top Width: 51mm, Bottom Width: 70mm, Height: 9mm, Thickness: 3mm Although not widely known, simply changing the saddle to cow bone noticeably changes the sound, even to the untrained ear. For more details, please search for explanations on video-sharing sites. Also, raising the string height improves the octave pitch, and lowering the string height loosens the string tension. These are sold as a set of 4. Even without special tools, the saddles are thin, so it's relatively easy to sand them down with sandpaper. Experiment with different heights to find your preferred setup. I can also offer advice, so feel free to ask anytime. In my opinion, Ukuleles generally ship with a high bridge. This is to avoid complaints about string buzzing and to allow for adjustment to the desired height later. However, many are sold online or in most music stores without adjustment. Most ukuleles are not at their best setup when purchased new. Most people are unaware that their ukulele isn't at its best setup and continue to use it that way. I hope you'll learn that you can make it easier to play and change the sound with some effort. Thank you for considering.
