Seymour created this classic humbucker combination while in England in 1974, and it remains his favorite today: an SH-4 JB for the bridge and SH-2n Jazz Model for the neck. Together they provide one of the most versatile humucker combinations available. The JB owes its popularity to over-wound coils, which provide high output with just the right amount of sustain and distortion - perfect for searing leads. Seymour matched the JB with a Jazz Model in the neck for calibrated output and clear, bright sound - perfect for articulate rhythm playing. This set is great for everything from hard blues to heavy rock. It comes with four-conductor cable for trick switching options. A wiring diagram and mounting hardware are included. The JB is designed for bridges with traditional string spacing of 1.925" or 48.9mm measured over the bridge pickup.
