K&K Sound Pure Bass — Acoustic 4-String Bass Guitar Pickup

The K&K Sound Pure Bass is a passive pickup system designed specifically for acoustic 4-string bass guitar — delivering the warm, natural and woody tone that acoustic bass players need when connecting to a PA system, amplifier or recording interface. Built on the same engineering principles as the acclaimed K&K Pure pickup family, the Pure Bass captures the full natural character of the acoustic bass without the compression, coloration or feedback problems that plague many acoustic bass amplification solutions. No battery required.

The K&K Pure Sound — Natural, Uncoloured Acoustic Tone

The defining characteristic of all K&K Pure series pickups is their commitment to natural, uncoloured sound reproduction. Where many acoustic pickups — particularly undersaddle piezo designs — produce a thin, compressed or plasticky tone that bears limited resemblance to the instrument's acoustic character, K&K's approach captures the instrument's natural voice with warmth and accuracy.

For acoustic bass guitar specifically, this matters enormously. The acoustic bass has a distinctive tonal character — a warm, woody fundamental with natural sustain, the resonance of the body contributing complex overtones and a depth that electric bass with flatwounds approximates but does not fully replicate. An acoustic bass through a poor pickup sounds like a bad electric bass. An acoustic bass through the K&K Pure Bass sounds like an acoustic bass.

Warm, Natural and Woody — What This Means in Practice

• Warm: The low fundamental frequencies of the acoustic bass are reproduced fully and naturally — no thin, bright or nasal quality that undersaddle pickups often produce on bass instruments.
• Natural: The pickup captures the acoustic character of the instrument without the electronic colouration that active onboard systems introduce — what you hear is the bass, not the pickup's personality.
• Woody: The body resonance and the characteristic tone of the wooden soundboard contribute to the amplified sound — the pickup captures not just the string vibration but the acoustic response of the instrument as a whole.

Passive Design — No Battery Required

The Pure Bass is a passive pickup — it requires no battery and contains no onboard preamp or electronics. The passive design produces a direct, natural signal from the piezo pickup elements without the tonal alteration or compression that active electronics introduce.

The passive output of the Pure Bass is optimised for connection to:

• An acoustic or bass amplifier with a high-impedance instrument input
• An active DI box for connection to a PA system or mixing desk
• The K&K Pure Preamp or similar acoustic preamp for volume control, EQ and impedance matching

For players who want volume control and basic EQ at the instrument, the K&K Pure Preamp — available separately at Angkor Music — is the recommended companion and is specifically designed to complement K&K passive pickup systems. Adding a preamp also improves the signal's impedance compatibility with a wider range of amplifiers and PA systems.

K&K Pure — The Same Trusted System

The Pure Bass is part of K&K Sound's acclaimed Pure pickup family — the same engineering approach that has made K&K one of the most respected acoustic pickup brands in the world. K&K Sound is a German company with decades of acoustic pickup development behind them, and the Pure series represents their refinement of the contact piezo pickup into a system that genuinely captures acoustic instrument character rather than approximating it.

Players who have experience with K&K Pure Mini, Pure Western or Pure Classic pickups on acoustic guitars will find the Pure Bass delivers the same quality of sound reproduction applied to the specific requirements of the acoustic bass.
