Why choose Seymour Duncan STC-2A 2-Band Tone Circuit For Active Pickups

  • 2-band active EQ provides transparent bass and treble shaping on any active pickup system
  • High headroom and low noise floor handle heavy dynamics and extended range tunings
  • Proprietary Slap Switch contour optimizes tone for percussive playing techniques
  • Single 9V battery (or dual 9V in series) powers the circuit with simple installation

Frequently asked questions

Will the SRB-1B fit my bass if it's not a Rickenbacker 4003?

No. The SRB-1B is engineered specifically for the Rickenbacker 4003 4-string bridge position and includes a phenolic mounting ring because it is slightly larger than the original. It is not compatible with other bass models.

Does the STC-2A work with passive pickups?

No. The STC-2A is designed exclusively for active pickup systems. It requires a 9V battery and will not function as a tone shaper for passive pickups without additional modifications.

Can I use coil-split options on the SRB-1B without rewiring my bass?

The SRB-1B ships with four-conductor wiring that enables coil-split, series/parallel switching, and in-phase/out-of-phase options, but you will need appropriate switching hardware (like a blend pot or toggle switch) wired into your bass control cavity to access these modes.

What is the Slap Switch contour on the STC-2A?

The Slap Switch is a proprietary alternative EQ voicing optimized for percussive playing and dynamic articulation. Two trim potentiometers on the circuit board let you adjust its character to suit your touch and playing style.
