The Seymour Duncan AJB‑3ASB Steve Bailey 4/5‑String Pickup Set with STC‑3AS combines calibrated active Jazz bass pickups and a 3‑band active EQ preamp for powerful, articulate tone with ultimate onboard control. Designed for 4‑ and 5‑string basses with rich harmonic response and flexibility.

The Seymour Duncan AJB‑3ASB Steve Bailey 4/5‑String Pickup Set with STC‑3AS is a complete active pickup system featuring custom‑voiced neck and bridge Jazz bass pickups matched to a 3‑band Tone Circuit (STC‑3AS) designed with Steve Bailey’s fretless bass tonal demands in mind. This set delivers precision, clarity and dynamic control from studio sessions to live performance. 

The STC‑3AS 3‑band active EQ preamp provides on‑board Bass, Mid and Treble controls, along with Blend and Master Volume for detailed tone shaping. An innovative frequency contour switch brings out fretless harmonics as well as mid‑range presence, giving you signature tonal versatility. The system works with most JJ basses that accommodate four control knobs and a single 9 V battery, with an optional dual‑battery setup for increased headroom.
