It is used to pick up sound waves traveling through solid objects. Signal amplification is low (3dB) to allow for the highest possible headroom. Marshmallow is a piezo disc contact microphone with a nice high-impedance preamplifier.
#Piezo preamps full
It has a 7.5 mega ohm input Impedance, which enables the piezo transducer to deliver its full potential. Additionally, the high impedance combined with the capacity of the cable to the preamp forms a low pass filter, making a piezo transducer often sound uninspiring.īigAmp Piezo is specially designed to overcome above issues. This prevents the transducer to deliver its potential output signal to the preamp and restricts transient response. The small form factor combined with the ease of use makes that every touring musician should have a BigAmp Piezo in their case or gigbag.Ī piezo transducer typically has an impedance of several mega ohms, which is much higher compared to the high-Z input of instrument preamps or mixing consoles. No hassle with batteries because BigAmp Piezo 's circuit is powered with phantom power. Bring your own high-quality DI everywhere. The output signal of your instrument will convert from an unbalanced to a balanced signal.Īn extra benefit might be BigAmp Piezo’s small size, making it super portable. It has a 1/4" female jack input which accepts signals from piezo transducers.īigAmp Piezo's low noise class A amplifier provides 3 dB of high-end amplification followed by a low impedance, balanced output buffer which reveals every detail and offers high-end sound quality. higher compared to the high-Z input of instrument preamps or mixing consoles. BigAmp Piezo is a small sized high-quality FET instrument preamp which performs equally well on stage as it does in a studio environment. preamp pedals are used to make acoustic-electric guitars sound more natural, and they do so by adding back body resonance, which are often lost in piezo. Instrument preamp for piezo pickups, high-quality FET instrument preamp.
