◆The HAPM function is, simply put, a general term for two functions: individual post length adjustment and Magnum Lock.

・The HAP function allows you to adjust the length of the tuning post for each individual tuning machine.
This enables fine-tuning of the tension for each string according to the characteristics of the guitar, the type of strings used, and the player's technique.
You can perform at your best, tailored to your playing environment.
It is also extremely useful for those who use alternate tunings, such as drop tuning.

・Magnum Lock is a function that makes tuning more stable and string changes much easier, as it sets the strings without winding them around the post.

GOTOH products boast a different level of accuracy than other manufacturers because they utilize the string's own tension to lock the string.

The first components to receive the vibration of a plucked string are the tuning machines, nut, and bridge. If you cut corners here, even a body and neck made of excellent wood will be meaningless.
