Seymour DuncanSteve Bailey 2-Band Jazz Bass System Set
Independent shopping perspective
The Korena take
For a fretless five-string JJ bass, the Steve Bailey 2-Band Jazz Bass System pairs calibrated active J pickups with Seymour Duncan’s STC-2ASB tone circuit. The layout combines blend, master volume, bass, and treble controls; pull up the volume knob to engage the frequency contour. Two trim pots provide contour presets inside the instrument. It needs cavity room for three knobs and a battery, and it is not a direct retrofit for a Fender Jazz V. Installation components are supplied as a pre-wired package.
Strong match
Who this is for
- Most 5-string fretless basses using a JJ pickup configuration and a three-knob control cavity.
- Players needing blend control, two-band EQ, and a pull-up frequency contour in one system.
Consider the trade-offs
When to look elsewhere
- A Fender Jazz V requiring a direct retrofit.
- Basses without space for three knobs and one battery.
