Specifications ◆Model Name: UPTL ◆Peg Button: UBB / Black ◆Color: BK / Black ◆Accessories: Bushings and washers required for installation ◆Head Thickness (Recommended): Can be installed on thicknesses of approximately 11.5 to 13.5mm "Accurate" tuning made "easy"! "GOTOH," a musical instrument parts manufacturer boasting the highest technology in Japan. By applying technology from other instruments, we have enabled accurate tuning for ukuleles. This peg is the long post model "UPTL" of the ukulele gear tuner "UPT." The difference is the length of the post, allowing it to be installed on ukuleles with thicker heads than the UPT. High tuning accuracy is necessary for cultivating a precise sense of pitch and for good performance. It is now a common understanding for any instrument that playing will not improve with ambiguous tuning. The ukulele's appeal lies in its accessibility, always by your side and easy to play, like a close friend, but accurate intonation has always been a challenge. This peg is a rare gear peg for ukuleles, using a "planetary gear mechanism" found in other instruments, and is lightweight for ukuleles with high technology! It's a dream tuner, weighing less than 15g per unit, including parts. The simple yet luxurious design, typical of GOTOH, shines through.
