The Radial PZ‑Deluxe is a studio‑quality acoustic instrument preamp and DI built into a pedal‑style enclosure for live and recording use. It features a semi‑parametric 3‑band EQ, low‑cut filter, and boost and mute footswitches to shape tone and control stage output. A special PZB piezo booster increases input impedance and gain for piezo pickups. Separate ¼″ outputs feed a stage amp and tuner, while a balanced XLR DI drives long cable runs to the PA. Other functions include polarity reverse and ground lift to reduce feedback and noise. The unit runs on a 15 V DC supply for increased headroom and dynamics.
