Seymour Duncan AJB-3ASB Steve Bailey Fundamental Fretless System 3-Band Tone Circuit
The Seymour Duncan AJB-3ASB Steve Bailey Fundamental Fretless System is a complete active pickup and EQ solution engineered specifically for fretless bass recording and studio work. Designed in collaboration with legendary fretless virtuoso Steve Bailey, this system captures the articulate, responsive character that fretless playing demands, with extensive onboard control to sculpt your tone across the frequency spectrum for precise tracking and mix-ready performances.
Electronics & Tone Shaping for Studio Control
This system combines calibrated neck and bridge active J Bass pickups with a 3-band EQ circuit that includes separate bass and treble controls, a dedicated midrange control, master volume, and blend control. The frequency contour switch—engaged by pulling up on the volume knob—provides an additional layer of sonic customization for dialing in your session tone, while two onboard trim pots allow you to preset the contour EQ to your specifications. Power is supplied by a standard 9-volt battery (accommodates 18 volts for enhanced headroom), delivering approximately 1,000 continuous hours of operation per battery set.
Build Quality & Reliability
The system is sized to accommodate both 4 and 5-string basses and includes all necessary mounting hardware plus a detailed wiring schematic for straightforward installation. Each unit is hand-built in Santa Barbara, California, ensuring the attention to detail and quality control expected from Seymour Duncan's boutique manufacturing standard.

Frequently Asked Questions
What makes this system different from a standard fretless bass pickup?
This is a complete active system designed specifically for fretless bass in collaboration with Steve Bailey. The calibrated active pickups are voiced to capture the articulate, responsive tone fretless playing demands, and the 3-band EQ with frequency contour switch gives you far more onboard control than passive pickups alone—letting you shape bass, treble, and midrange independently.
