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 players needing versatility in live and studio settings, 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, while the mic captures natural resonance and room tone, with full copper shielding minimizing noise and interference.

Power & Control

Two AA batteries power an 18-volt preamp delivering twice the dynamic range of standard 9-volt systems, accommodating harder playing and reducing headroom issues. 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.

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.
