KNA Pickups DB-1 Portable Double Bass Passive Piezo Pickup | Piano Gallery, Idaho Falls
The KNA DB-1 is a passive piezo pickup designed specifically for double bass — a clean, nondestructive amplification solution that faithfully reproduces the full dynamics and tonal range of the instrument without requiring any modifications that could damage the instrument's finish, bridge, or tailpiece. The wood-encased piezo sensor installs in the eye slot of the bridge and is held securely in place with friction, while the 1/4" jack housing attaches nondestructively to the tailpiece via a screw assembly at the string eye. Neatly finished shim discs ensure a precise, secure fit across different bridge dimensions, and the completely passive design works directly with any bass amplifier or preamp without a battery or external power source. For orchestral, jazz, and working double bassists who want reliable, natural-sounding amplification without touching a drill or altering their instrument, the KNA DB-1 is an excellent solution.
Product Overview
The DB-1's bridge-mounted installation method is the key to its natural tonal reproduction. By placing the wood-encased piezo element directly in the eye slot of the bridge — the point where string vibration transfers most directly into the instrument's body — the pickup captures the full dynamic range and tonal character of the double bass at its most resonant and responsive point. The wood enclosure contributes to tonal sensitivity by allowing the piezo element to respond to vibrations with the natural acoustic properties of wood rather than the filtered response of plastic or metal housings, producing a more faithful, organic representation of the instrument's voice.
Installation is entirely nondestructive throughout. The piezo sensor fits into the bridge eye slot and is held by friction — with the included shim discs ensuring a secure, properly fitted installation across different bridge slot dimensions without adhesive or permanent alteration. The 1/4" jack housing attaches to the tailpiece via a screw assembly at the string eye, keeping all mounting points on removable hardware rather than the instrument's body or finish. Both mounting points can be removed completely without leaving any trace on the instrument, making the DB-1 a safe choice for valuable and vintage double basses where preservation of the original condition is essential.
The passive circuit operates at a maximum impedance of 200 ohms and requires no battery — connecting directly via the included 11.42" lead cable to any bass amplifier, preamp, or DI box for immediate, battery-free performance. The short lead cable keeps the connection between the bridge and output jack tidy and unobtrusive during performance.
