The Complete Guide to Electric Double Bass Guitar

An electric double bass guitar is a modern instrument combining the scale and physical presence of an acoustic upright double bass with electric pickups, preamps, or solid-body construction. For jazz, classical, and ensemble musicians, the electric double bass offers the acoustic depth and resonance of a traditional upright whilst adding electronic amplification, flexibility, and portability. Whether you are a classically trained double bassist seeking an amplifiable rig or a contemporary jazz musician exploring hybrid tones, the electric double bass extends the possibilities of what a traditional acoustic instrument can become.

What Is an Electric Double Bass?

An electric double bass comes in two main forms: an acoustic double bass fitted with electric pickups and a preamp, or a solid-body electric bass designed to the scale and proportions of a double bass. The former preserves the acoustic resonance of the upright whilst adding electric amplification. The latter combines the solidness of electric construction with the size and appearance of an upright for ensemble contexts.

Both designs produce tones deeper and more resonant than a standard four-string bass guitar, maintaining the traditional character of double bass music.

Acoustic Double Bass with Electronics

Many professional double bassists add piezo pickups and preamps to existing acoustic uprights, preserving the instrument's acoustic properties whilst enabling amplification. A quality pickup senses the vibration of the bridge and strings, converting that energy into an electrical signal the preamp processes and amplifies. This approach maintains the acoustic warmth of the double bass whilst allowing live amplification and recording capability.

Retrofit kits are available, and many luthiers can install systems into existing basses at reasonable cost.

Solid-Body Electric Double Basses

Modern builders create fully solid-body electric double basses scaled to traditional upright proportions (typically 41–44 inches). These instruments offer the visual presence of an upright double bass, the amplification and feedback resistance of electric basses, and often lower weight than acoustic uprights. They suit jazz, classical crossover, and contemporary ensemble contexts where a double bass is essential but acoustic amplification is problematic.

Scale and String Configuration

Most electric double basses maintain the four-string configuration of traditional upright basses (G-D-A-E, one octave below a four-string guitar). Some feature five strings (adding a low B) for extended range. The scale length (distance from bridge to nut) is longer than bass guitars, typically 40–44 inches, maintaining the acoustic playing ergonomics that trained double bassists expect.

This longer scale produces the lower, warmer fundamental frequency characteristic of traditional double bass.

Tone and Sound Character

An electric double bass produces a deeper, more resonant tone than a standard bass guitar. Frequencies sit lower, and sustain is longer. The playing feel—string tension, bridge response, and harmonic development—more closely resembles an acoustic upright than a rock bass rig. For jazz standards, classical ensembles, and folk contexts, an electric double bass preserves traditional character whilst enabling modern amplification.

Amplification and Connectivity

Electric double basses typically include onboard preamps with volume and tone controls, sometimes parametric EQ. Many feature XLR balanced outputs for direct recording or longer cable runs to amplifiers. USB connectivity on premium models enables direct recording to DAWs. Standard 1/4" outputs also work with any bass amplifier.

The electrical integration varies by builder; some focus on transparency (amplifying the acoustic character), others add tone shaping and colour.

Weight and Portability

Acoustic double basses are notoriously heavy (80–150 pounds). Solid-body electric double basses weigh typically 8–15 pounds, dramatically reducing transport burden. An electronically amplified acoustic upright falls between, depending on how much electronics are added. For gigging musicians, portability is often as important as tone.

Playing Technique

An electric double bass demands the same technique as an acoustic upright—bow control, vibrato, intonation awareness, and finger strength all matter. The electric amplification does not change the fundamentals of playing; it simply enables amplification and studio flexibility. Musicians trained on acoustic double bass transition easily to electric versions; the playing technique remains essentially unchanged.

Jazz and Classical Contexts

Jazz bassists use electric double basses to bridge the acoustic warmth of traditional upright sound with the amplification and flexibility of modern music-making. Classical chamber ensembles sometimes use electric doubles in electric/acoustic hybrid ensembles. Contemporary composers often write for electric double bass alongside electric strings and amplified classical instruments, exploring the hybrid tone.

Cost and Investment

Acoustic double bass with retrofit electronics costs £2,000–£8,000 (instrument plus pickup installation). Solid-body electric double basses from established builders cost £1,500–£5,000. Top-tier custom instruments exceed these ranges. For context, new acoustic double basses without electronics cost £1,500–£10,000; adding quality amplification via retrofit adds £500–£2,000.

Maintenance and Setup

An electrically amplified double bass requires occasional preamp battery replacement (usually 9V or internal rechargeable), cable management, and regular output checks. Acoustic double basses additionally need humidity control, bridge adjustment, and string maintenance. Solid-body electric instruments need only normal instrument care—strings, occasional setups, and cable maintenance.

Conclusion

An electric double bass extends the possibilities of traditional double bass playing into amplified and studio contexts without sacrificing the acoustic character and deep resonance that make the upright double bass essential to jazz, classical, and ensemble music. Whether you retrofit an existing acoustic instrument or choose a modern solid-body electric design, an electric double bass offers portability, amplification, and the distinctive tone that defines traditional bass music. For serious double bassists exploring hybrid or amplified ensembles, or for classically trained musicians seeking modern performance flexibility, an electric double bass bridges centuries of bass tradition with contemporary amplification.
