You can finely adjust the tension of each string to match the individuality of the guitar, the characteristics of the strings used, and the player's habits. You can play in the best condition to suit your playing environment. It is also very useful for those who use drop tuning or other alternate tunings. ・Magnum Lock is a function that makes tuning less likely to go out of tune and makes string changes very easy because the strings are set without being wrapped around the shaft. GOTOH products utilize the tension of the strings themselves to lock the strings, boasting a level of accuracy that is on a different level from other companies' products. The pegs, nut, and bridge are the first to transmit the vibration of the played strings. If you cut corners here, even a good wood body and neck are meaningless.
