What is the difference between BigAmp and BigAmp Piezo?

The main difference between the BigAmp and BigAmp Piezo lies in their intended applications and impedance characteristics:


  • Designed for general amplification purposes.
  • Has an impedance of 1MOhm.
  • Suitable for a wide range of instruments and audio sources.

BigAmp Piezo

  • Specifically tailored for amplifying piezoelectric pickups commonly found in acoustic instruments like acoustic guitars, violins, and other stringed instruments.
  • Features a higher impedance of 7.5MOhm, optimized for piezo pickup systems.
  • Provides enhanced signal clarity and fidelity for piezo pickups.

Both models offer high-quality amplification, but the BigAmp Piezo is specialized for piezoelectric pickups, ensuring the best performance for acoustic instruments equipped with such pickups.
