Radial Tonebone PZ-Deluxe, Acoustic Instrument Preamp, Radial Item R800 7320.
The PZ-Deluxe is an instrument preamp with a low-noise front end that is capable of exceptional dynamics to adapt to all instruments including acoustic guitar, upright bass, mandolin and violin, no matter what type of pickup system is being used. A special PZB gain stage can be activated for use with instruments that have piezo transducers, increasing the input impedance to 10Mohms and eliminating the harshness that is sometimes associated with those pickup systems.
