Seymour Duncan TB-APH1B "Alnico II Pro" Trembucker pickup. Black. Trembucker spaced for guitars with tremolo bridges or string spacing over 2".
After players heard the Alnico II Pro single-coil models, many asked for that same sweetness in a humbucker version. The only way to get that sound is to use the Alnico II musical magnets with a new coil winding.
The result is a warm, sweet tone with more natural string vibration for great sustain and balance. Four conductor cable for split/phase options. Includes wiring diagram and mounting hardware. Made in the USA.
