Triton Audio BigAmp Piezo｜High-Impedance FET Preamp for Piezo Pickups & Instruments
The BigAmp Piezo is a compact, high-quality FET instrument preamp designed specifically for piezo pickups used in acoustic guitars, violins, double basses, ukuleles, and other instruments. With its Class-A low-noise circuit and ultra-high 7.5 MΩ input impedance, it captures every detail of your instrument’s tone while delivering a clean +3 dB gain boost for improved signal strength and clarity.
Equipped with a built-in low-impedance balanced output buffer, the BigAmp Piezo converts unbalanced piezo signals into professional balanced XLR output, ensuring stable and noise-free long cable runs. Powered directly by 48V phantom power, with a rugged metal housing for durability and EMI shielding, the BigAmp Piezo is the perfect solution for DI boxes, live stage, studio recording, and rehearsal setups.
