Radial Tonebone PZ-Deluxe Acoustic Preamp
The Radial Tonebone PZ-Deluxe is a studio quality instrument preamp combined with a direct inject (DI) box equipped with a full array of features for live stage use.
The Radial Tonebone PZ-Deluxe offers studio specification pre amplification for acoustic instruments with a low noise front end capable of exceptional dynamics no matter what type of pickup system is used. For piezo transducers a special PZB gain stage increases the input impedance to 10 meg-Ohms- eliminating the explosive peaks that are common in other systems. The PZ Deluxe eliminates the need for a separate preamp - important for those that do not want to cut a hole into their vintage guitar. The control panel is featured with input gain 3-band semi-parametric EQ with variable mid-frequency a three position low frequency filter and 180 DEGREE polarity reverse switches to help eliminate acoustic hot spots that can cause audio feedback. A guitar level output splits the sound to the artists stage amp with the built-in Radial direct box feeding the PA system. A separate tuner output provides further flexibility for signal routing in pedal board setups. A variable power booster with set & forget level switching gives you the control to punch through the mix when needed. With a compact design the Radial PZ-Deluxe is easily transported and is built to withstand a life on the road - offering a high quality audio output and seriously flexible signal routing capability.
