Description
Seymour Duncan ASB-3ASB Steve Bailey 6-String Fretless Bass System
The ASB-3ASB is a complete active pickup and tone circuit system engineered specifically for the 6-string fretless bass, delivering the articulate, punchy response that defined Steve Bailey's signature sound. This hand-built system combines responsive soapbar pickups with a sophisticated 3-band active EQ to sculpt everything from deep lows to singing highs with surgical precision. Built in Santa Barbara, CA, this is serious electronics for recording sessions and productions that demand control and clarity from a fretless instrument.
Tone & Electronics
The 3-band Tone Circuit provides master volume, blend control, mid-range adjustment, and concentric bass and treble controls—all wired to high-quality potentiometers on a pre-assembled harness. A special frequency contour switch engages by pulling up the volume control, giving you instant access to frequency shaping without adding extra knobs to your control cavity. Powered by a single 9V battery with approximately 1,000 continuous hours of runtime per set, the system can also run two batteries in series for added headroom—critical for extended studio sessions.
Installation & Integration
Designed to retrofit into any fretless bass with space for four control knobs and a single 9V battery cavity, this system includes all necessary mounting hardware and a battery clip for hassle-free installation. The included black anodized, knurled, dome-style knobs provide secure, tactile control and a professional appearance once mounted, ensuring reliable operation and repeatable settings across takes and sessions.

Frequently Asked Questions
What bass models does this fit?
The ASB-3ASB retrofits into any 6-string fretless bass that has space for four control knobs and a standard 9V battery cavity. Installation requires no modification to your instrument if those cavities already exist.
How long does the battery last?
A single 9V battery runs approximately 1,000 continuous hours. The system can also run two 9V batteries wired in series if you want extra headroom and longer runtime between changes.
What controls do I get?
You get master volume, blend control for pickup mixing, dedicated bass and treble controls, mid-range adjustment, and a special frequency contour switch that engages by pulling up the volume knob—giving you five layers of EQ without extra knobs cluttering your control cavity.
Does it come pre-wired?
Yes. The harness arrives fully pre-assembled with high-quality potentiometers, and includes all mounting hardware, battery clip, and black anodized knurled dome-style knobs ready to install.
Why choose this over a passive pickup system?
Active electronics give you the gain, headroom, and surgical EQ control that fretless bass needs to cut through a mix with clarity and definition. The Seymour Duncan ASB-3ASB combines responsive soapbar pickups with precision tone-shaping that passive systems cannot match.
Do I pay sales tax on this order?
