◆About installation on instruments

When equipping the existing musical instrument with GOTOH products, processing of addition to the musical instrument side may be necessity. If attachment impossible without processing is carried out, there is a possibility of leading to breakage of a musical instrument. Please check size etc. well before purchase. Moreover, We recommend that replasment work is requested from specialists, such as a repair shop. In addition, about breakage of the musical instrument when replacing, an accident, etc., it shall be considered as self-responsibility, and our shop shall not take any responsibility.


◆ Notes on machine head replacement

When installing the G - GOTOH machine head by yourself, do not over - tighten the screw fixing the thread winding. Wood screws of JIS standard are used for the G - GOTOH machine head, but if you tighten too strongly it may cause the head of the screw to be cut off. Since it is not a tapping screw, such a phenomenon may occur even if the pilot hole is not appropriate. In addition, please do not easily remove the knob or decorative cap because it will cause breakdown or damage.

* The proper size of the prepared hole will change according to the hardness of the wood, so you can not specify the size unconditionally.

* Manufacturer's tightening torque etc. are not specially specified.
