The SH-4 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 matches the JB with an SH-2n Jazz Model in the neck for calibrated output and a clear, bright sound - perfect for articulate rhythm playing. This set is great for everything from hard blues to heavy rock, and includes four-conductor cable trick switching options. Wiring diagram and mounting hardware included.
