K&K Sound Double Big Twin 4-Head Upright Bass Pickup

Capture the natural character of your upright bass with the K&K Sound Double Big Twin. Designed particularly for jazz bass players, this four-head passive piezo pickup system provides clear articulation, rich low frequencies and balanced response across all four strings.

Balanced Sound Across Every String

Four individual transducer heads capture string vibrations separately, helping deliver consistent volume and definition. Its extended frequency response reproduces both the warmth of low bass notes and the clarity of finger attack.

Natural, Expressive Jazz Bass Tone

Designed for pizzicato playing, the Double Big Twin delivers a detailed acoustic response that preserves the character of your instrument, making it well suited to jazz rehearsals, recording and live performances.

Easy, Non-Invasive Installation

The transducers attach to the bass bridge using the supplied double-sided adhesive film, without requiring permanent instrument modification. A dedicated clamp secures the output jack between the strings below the bridge.
