Description
Seymour Duncan Wavelength™ Duo Steel String Pickup
The Wavelength Duo delivers a dual-source amplification system that captures both the articulate transducer response and ambient mic character in a single, compact unit. This hybrid design excels for gigging players needing versatility across live venues and studio sessions, offering independent control over piezo and condenser elements without the bulk of traditional multi-pickup systems.
Dual-Source Architecture
The system pairs an under-saddle piezoelectric transducer with an omnidirectional condenser microphone mounted in a shock-absorbing visco-elastic polymer cradle. The piezo element provides consistent string-to-string response on stage, while the mic captures natural resonance and room tone—essential for adapting to different venues. Full copper shielding minimizes noise and interference, keeping your signal clean even in electrically hostile environments.
Power & Control
Two AA batteries power an 18-volt preamp delivering twice the dynamic range of standard 9-volt systems, so harder playing and aggressive transients won't push you into distortion. Dual lightweight, low-profile knobs control master volume and microphone volume independently, while stereo wiring allows tip/ring separation of pickup and mic signals for maximum mixing flexibility—ideal for soundcheck adjustments or working with a monitor engineer.
Key Features
- Under-saddle piezoelectric transducer with unitary piezo element for even string response
- Omnidirectional condenser microphone with dedicated volume control
- Microphone mounted in special absorptive visco-elastic polymer shock mount
- Full coverage copper shielding on pickup assembly
- 18-volt, low-noise, high-input impedance preamp
- Two AA battery power supply
- Twice the dynamic range of typical 9-volt preamp systems
- Two lightweight, low-profile control knobs for master and mic volume
- Stereo wiring option with tip/ring connections for channel separation
- Microphone channel with two stages of low frequency roll-off
The Wavelength Duo stands out for players who demand transparent amplification with the flexibility to blend acoustic character and piezo punch in real time, whether running straight into a board or monitoring through a wedge.

Reviews
At a Glance
The Seymour Duncan Wavelength Duo is a hybrid under-saddle pickup and condenser mic system that captures both articulate transducer response and natural room tone in one compact unit. Intermediate to professional players on tour or performing regularly will appreciate the independent volume controls, 18-volt preamp headroom for dynamic playing, and stereo wiring that lets you blend piezo punch with ambient character on the fly. It outperforms single-source systems by delivering transparent amplification without the bulk of traditional multi-pickup rigs.

Frequently Asked Questions
What's included in the box, and will it work with my acoustic guitar right away?
The Wavelength Duo includes the under-saddle transducer, condenser mic assembly with shock mount, 18-volt preamp, dual control knobs, stereo wiring harness, and two AA batteries. Professional installation is recommended to properly seat the piezo element under the saddle and position the mic; it is not a plug-and-play retrofit for most instruments.
How does the dual-source design compare to a single piezo pickup?
The Wavelength Duo combines an under-saddle piezo for consistent string-to-string response with a condenser mic that captures room tone and natural resonance. You get independent volume control over each source and stereo wiring that lets you blend or separate the two signals, offering far more tonal versatility than a piezo-only system in both live and studio settings.
How long do the AA batteries last, and is the 18-volt system really worth it?
Battery life varies with playing intensity and mic volume settings; typical use ranges from several weeks to a few months. The 18-volt preamp delivers twice the dynamic range of standard 9-volt systems, meaning harder picking and strumming won't clip the preamp and you'll have more headroom for live performance and recording without distortion.
Can I use just the piezo or just the mic, or do I have to blend both?
Yes—the dual lightweight knobs let you adjust master volume and microphone volume independently, so you can dial either source up or down to taste. Stereo wiring also allows tip/ring channel separation, letting you send the pickup and mic to separate mixer inputs or effects chains for complete mixing control.
What genres and playing styles is this pickup designed for?
The Wavelength Duo excels in live performance, studio sessions, folk, and acoustic touring—any context where you need articulate transducer response and natural acoustic character. It is best suited for intermediate, advanced, and professional players; beginners and practice-only setups typically benefit from simpler, more affordable solutions.
Do I pay sales tax on this order?
