Passive piezo design
The pickup operates without a battery or external preamp.

Independent shopping perspective
KNA’s DB-1 is a passive double-bass pickup built around a wood-encased piezo sensor. The sensor fits into the bridge by friction, and its included 1/4-inch output jack attaches to the tailpiece, so the bass can connect to an amp or PA without permanent modification. No battery or external preamp is required. The design is intended to reproduce the double bass’s dynamics and acoustic character when amplification is needed for stage or studio use.
