The BigAmp Piezo redefines what’s possible when you need professional-grade amplification in an incredibly compact form factor. This high-quality FET instrument preamp excels both on stage and in studio environments, specifically engineered for piezo transducers with its impressive 7.5 mega ohm input impedance that allows your transducer to reach its full sonic potential.
With its modest 3dB signal amplification, the BigAmp Piezo prioritises maximum headroom over excessive gain, ensuring clean, transparent sound reproduction. The unit’s remarkably small size means you can position it as close to your transducer as possible, minimising cable capacitance issues that can compromise your signal quality. This compact design also makes it exceptionally portable for musicians on the move.
Setup couldn’t be more straightforward – simply attach your BigAmp Piezo to an XLR cable, connect your electric guitar, bass, or any instrument with a jack output, and engage phantom power. The unit feeds directly into the balanced input of your preamp or audio interface, while a short TS/Jack cable between the BigAmp and your instrument will optimise sonic results.
At its core, the BigAmp Piezo features a low-noise FET amplifier circuit paired with a low-impedance balanced buffer. This combination captures every nuance with pinpoint accuracy, ensuring high-end sound quality that reveals the true character of your instrument.
