* C-A-R-D 3/3 is suitable for SD90.

C - Carbon Fiber

Made from a specially formulated carbon fiber composite resin, CARD is both lightweight and extremely durable.

A - Align Center

CARD features a centering guide molded into the base that insures correct string post positioning in relation to the tuner bushing.

R - Resonant

The high-density CARD material transfers string vibration to the instrument headstock more efficiently, improving sustain and harmonics.

D - Defend

The CARD base is .05 mm thicker than the inside cavity of the tuner cover and acts as a spacer to prevent damage to the headstock finish due from sharp metal edges and over-tightening of mounting screws.


- NOTE -

C・A・R・D is designed specially to fit Gotoh SD Series machine heads, and it may not work with other models/brands of tuners.

C・A・R・D will now be offered as standard equipment with Gotoh SD510/SDS510 models, replacing the previously offered self-center guide.

C・A・R・D idea and design are Patent pending.

◆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.

◆ 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.
