Frequently asked questions
Which system fits my bass?
The AJB-3ASB accommodates 4 and 5-string basses. The ASB-3ASB is engineered for 6-string fretless basses. Both systems require space for four control knobs and a 9V battery cavity.
What is the main pickup difference?
The AJB-3ASB uses calibrated active J Bass pickups (neck and bridge). The ASB-3ASB uses responsive soapbar pickups. J-style pickups typically offer more articulation in tight spacing; soapbars provide broader tonal palette and wider string coverage.
Are the tone circuits the same?
Both feature 3-band active EQ with master volume, blend, midrange control, and concentric bass/treble controls. Both include a frequency contour switch activated by pulling the volume knob. Both run on a single 9V battery (approximately 1,000 hours) with optional dual-battery configuration for added headroom.
How difficult is installation?
The AJB-3ASB includes a detailed wiring schematic and mounting hardware. The ASB-3ASB includes a pre-assembled harness and mounting hardware, potentially simplifying installation further. Both are hand-built in Santa Barbara with quality construction standards.
