TUNING
Most guitar players tune their guitar by themselves as they like.
Do not adjust tunings of a customer’s guitar at usual repairs, because the tunings may be re-adjusted by a
customer. Only after replacing the neck, the bridge or the pickup, adjust a certain tuning item shown in the
following table.
Tools/Equipments required
4 mm hexagon key (Accessory tool)
1.5 mm hexagon key (Accessory tool)
