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.
