The STC-2P, designed for passive pickups, features concentric bass and treble controls, a master volume, a blend control, and our proprietary Slap Switch. The treble control can produce a wide ranging, extremely usable response that is brilliant, yet smooth without being brittle. The bass can be reduced to tighten up a boomy instrument, or it can be increased to add warmth and punch. The Slap Switch is a pushpull located on the volume control. Pulling up on the volume knob will engage the special EQ contour voiced specifically for slap playing. The two small trim pots on the circuit board can be tweaked to preset the slap contour EQ just the way you want.

The STC-2P Tone Control is voiced to work in any bass that is equipped with two passive pickups and has space for 3 control knobs (volume/slap switch, blend, concentric bass and treble controls) and a single 9v battery in the control cavity. Two 9v batteries can be wired together in series for added headroom.

We include all necessary mounting hardware: high-quality potentiometers on pre-wired harness; battery clip; and black anodized, knurled, dome-style knobs.

Steve Bailey is a world-renowned player whose signature 6-string fretless bass demands a pickup system that can handle a diverse range of musical styles with equal power and finesse. Steve wanted to use one pickup that would handle all his musical efforts, both on stage and in the studio. Steves wishes were granted with this pickup/preamp set.

Diverse tone and articulate, detailed performance from the neck and bridge active soapbar pickups can handle the wide range of musical styles Steve performs. This one set of pickups takes Steve from a solo performance with slap grooves and shimmering harmonics to a straight-ahead rock show to a jazz tracking session with ease. His tone is crystal clear yet powerful, punchy yet refined. If you have exacting standards about your tone, we believe this set is for you.

The Phase I soapbar pickups fit in a 466 x 127 (the traditional P4) routed 6-string bass. The 2-band Tone Circuit provides bass and treble controls, a master volume, a blend control, and our special frequency contour switch. This preamp was voiced by Steve Bailey to have two bands of focused EQ, together with a switch that engages a frequency contour optimized to bring out fretless harmonics as well as mid-range boost. The frequency contour is engaged by pulling up of the volume control. There are two small trim pots on the circuit board can be tweaked to preset the frequency contour EQ just the way you want.

This system can be installed in any fretless bass that has space for 3 control knobs (volume/freq switch, blend, concentric bass and treble controls) and a single 9v battery in the control cavity. Two 9v batteries can be wired together in series for added headroom. We include all necessary mounting hardware, high-quality potentiometers on pre-wired harness, battery clip, and black anodized, knurled, dome-style knobs. Battery life is approximately 1,000 continuous hours per set.

Hand built in Santa Barbara, CA, the Steve Bailey System includes neck and bridge pickups and is available in 2-band or 3-band Tone Circuit built for use with active pickups.

We designed our Active Soapbar bass pickups to be the perfect blend of a traditional active pickup’s punch and snap and a vintage passive pickup’s warmth and tone. The dynamics and response are true, with just a hint of tonal coloring that is musical and not extreme. The sound of the ASB is natural, with an even bass, mid, and treble response that’s perfect for fingerstyle or slap.

The onboard active preamp gives you more overall volume and presence than you can typically get from a passive pickup. Our internal split-blade design allows for the best string-to-string balance of any soapbar bass pickup. The ASB-5 is a direct replacement for EMG 40 sized soapbars.

Many bassists combine the ASB pickups with our STC-2A or STC-3A Tone Circuit preamps to add precision EQ sculpting. Battery life is approximately 1,000 continuous hours per set and we include all necessary mounting and wiring hardware.

Blackouts Bass Soapbar high-output active bass pickups were designed to make getting an aggressive bass tone simple. Instead of having to EQ a lesser pickup into submission, we voiced the Blackouts with big bass tone in mind. We went all-in on this one, with a huge dynamic range, thunderous lows, and crisp highs that deliver forceful raw energy, all focused into a super-responsive soapbar. The 5-string version extends those qualities to handle even more boom.

Fingers, thumbs, and plectrums are all at home with these pickups, handling the heaviest hands and lightest playing styles with equal precision. String-to-string balance is assured with the Blackouts’ dual-blade design. The 4-string model is a direct replacement for EMG 35-sized pickups and the 5-string version is a direct replacement for the EMG 40.

Many players combine the Blackouts Bass Soapbar with a Blackouts 2-band tone circuit (STC-2C-BO or STC-2S-BO) to add precision EQ sculpting. These EQs can extend tonal possibilities from traditional to modern tones, and we include all necessary mounting and wiring hardware.

Steve Bailey’s fretless bass tonal demands range from the bite of a blues trio to the edge of a power trio to the warmth of a jazz trio to the extremes of a bass duo. We designed this system to deliver ultimate control from the studio to the stage.

Starting with calibrated neck and bridge active J bass pickups voiced to enhance Steve’s fretless playing, we then added our 2 band Tone Circuit (STC-2ASB) for a complete system. Our Tone Circuits will add a tremendous amount of on-board tonal versatility to any dual pickup bass. This design enables players to boost or cut specifically focused frequencies in order to achieve signature tones and to dial in a great sound no matter what the situation. We even added two small trim pots on the circuit board can be tweaked to preset the frequency contour EQ just the way you want.

This STC-2ASB Tone Circuit provides bass and treble controls, a master volume, a blend control, and our special frequency contour switch. This preamp was voiced by Steve Bailey to have two bands of focused EQ, together with a switch that engages a frequency contour optimized to bring out fretless harmonics as well as mid-range boost. The frequency contour is engaged by pulling up of the volume control.

This system will work in any JJ bass that has space for 3 control knobs (volume/slap switch, blend, concentric bass and treble controls) and a single 9v battery in the control cavity. Two 9v batteries can be wired together in series for added headroom. Battery life is approximately 1,000 continuous hours per set.
