Frequently asked questions
Which one do I need for my bass?
If your bass currently has active pickups with onboard electronics, choose the STC-2ASB. If your bass has passive pickups without onboard preamp, choose the STC-2PSB. The STC-2PSB includes a complete pre-wired harness designed for passive instrument integration.
Are both circuits suitable for fretless bass?
Yes, both are listed as suitable for fretless bass. The STC-2ASB emphasizes articulate, smooth tone with high headroom for responsive playing. The STC-2PSB has frequency contours specifically optimized for fretless harmonics and mid-range boost.
What's the difference in battery options?
Both circuits operate on a single 9V battery as standard. Both offer the option to wire two 9V batteries in series—the STC-2ASB uses this for increased headroom and dynamic range, while the STC-2PSB uses it for increased headroom and extended battery life.
Do I need soldering skills for installation?
The STC-2PSB ships with a pre-wired harness and includes potentiometers and knobs, making passive installation more straightforward. The STC-2ASB is designed for active pickup systems that typically already have control cavities set up for electronics, but installation complexity depends on your specific instrument's current wiring.
