* C-A-R-D 6 is suitable for SD91.
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.
