KNA DB-1 Double Bass Pickup

The KNA DB-1 is a portable, bridge-mounted piezo pickup designed to capture the full tonal depth and dynamic range of your double bass — no modifications required. Engineered for natural, transparent sound reproduction, the DB-1 combines precision design with an easy, non-destructive installation process, making it the perfect choice for players seeking reliable amplification without altering their instrument.

The pickup features a lightweight, wood-encased piezo sensor that installs securely in the bridge’s eye slot using friction, ensuring maximum tonal sensitivity.
