Easy tuning to "accurate" pitch! GOTOH, a musical instrument parts manufacturer boasting the highest technology in Japan. By applying the technology of other instruments, we have made accurate tuning possible even for ukuleles. These pegs are the long post model "UPTL" of the ukulele gear tuner "UPT". The difference is the length of the shaft, and it can be installed on ukuleles with thicker heads than the UPT. High tuning accuracy is necessary to cultivate an accurate sense of pitch and to play well. It is now a common belief for any instrument that playing will not improve with ambiguous tuning. Ukuleles are attractive because they are always at your side and can be played easily, like a close friend, but they have always been weak in terms of accurate pitch. These pegs use a "planetary gear mechanism" found in other instruments, which is rare for ukuleles. They are lightweight for ukuleles with high technology! It's a dream tuner, with each part weighing less than 15g, including the parts. The design is simple yet luxurious, typical of GOTOH. You can check the screw hole spacing and dimensions from the photos. #UkulelePegs
