Discrete Class A Engineering and Real-Time Pickup Interaction

Fully Discrete Studio-Grade Preamp Circuitry

The Seymour Duncan Pickup Booster Mini packs two decades of transparent signal conditioning into an ultra-compact, pedalboard-saving mini housing. Engineered with a fully discrete, studio-grade Class A circuit topology, this pure analog line driver enhances output levels without coloring your instrument's baseline character. Featuring a premium push-pull output design, the circuit maximizes drive capabilities across long, demanding signal chains. Operating at unity gain (0dB), the pedal functions as an ultra-clean impedance buffer, counteracting high-frequency signal loss and preserving your raw picking attack over extensive cable runs.

Three-Way Resonance Manipulation and Peak Shifting

Standing apart from standard linear boosters, this utility unit incorporates a dedicated Resonance Switch that directly manipulates the behavior of passive guitar pickups. In the center position (0), the circuit delivers an entirely transparent, uncolored gain multiplication. Flipping the switch to Position 1 shifts the resonant peak downward to mimic the warm, chunky characteristics of a vintage humbucker, adding muscle to thin single-coil configurations. Moving the switch to Position 2 drops the resonant peak further to emulate a thick, high-output humbucker tone, introducing focused low-mids and exceptional note articulation that allows solo passages to cut cleanly through dense stage tracking.

Creative Rig Integration and Circuit Optimization

Single-Coil To Humbucker Instrument Emulation

Placing the device at the absolute front of your pedalboard layout allows a single guitar to cover vast tonal ground during a live performance. By activating the pedal with the Resonance Switch set to Position 1, a standard Stratocaster or Telecaster can instantly transition into a thick classic rock or blues machine. This configuration shifts your single-coil architecture into a warm, mid-forward humbucker profile, saving you from swapping physical instruments mid-set.

High-Voltage Power Attenuation and Amplifier Saturation

Powering the fully discrete circuit lane with a regulated 18VDC supply expands internal headroom, lowering total harmonic distortion below 0.02% while providing up to 25dB of clean output multiplication. Staging this high-headroom boost right before a vintage tube amplifier pushes the preamp tubes into a screaming, saturated breakdown. This interaction replicates a blistering vintage amplifier voice while maintaining precise definition and snappy touch response across your picking attack.

THIS PEDAL REQUIRES AN EXTERNAL 9V TO 18V REGULATED DC ADAPTER WITH A CENTER NEGATIVE POLARITY CONFIGURATION. CURRENT CONSUMPTION MEASURES 4.5mA AT 9V AND 11mA AT 18V. THE UNIT DOES NOT SUPPORT INTERNAL BATTERIES. DO NOT EXCEED 18V DC OR USE UNREGULATED POWER SUPPLIES, AS PERMANENT COMPONENT DAMAGE MAY OCCUR AND YOUR WARRANTY WILL BE VOIDED.
