Pick Up The Most Powerful Acoustic Preamp Ever To Be Put Inside A Pedal And Fall In Love With Your Tone All Over Again - The Radial Tonebone PZ-PRE Acoustic Instrument Preamp Pedal

The Radial Tonebone PZ-Pre™ is the most powerful acoustic preamplifier ever to be put inside a pedal. And when we say acoustic, we do not just mean acoustic guitar - we mean ANY acoustic instrument including banjo, violin, cello, mandolin, contrabass, bouzouki or lute. The magic lies in the combination of high performance 100% discrete class-A PZB piezo boosters, an ultra-quiet preamp circuit that will adapt to any pickup system and a host of connectivity options that will put you in total control.

The PZ-Pre is equipped with two inputs for quick instrument changes on stage. These can also be combined to blend two pickups together if you so desire. Features include a powerful yet warm sounding semi-parametric EQ to tailor your sound, feedback eliminating controls including a dual-Q notch filter to surgically remove feedback, a high-pass filter to cut low frequency resonance, and a phase reverse switch to eliminate hot spots on stage. It is also equipped with a host of outputs: a ¼" hi-Z instrument out for an on-stage amp, a pre-EQ balanced XLR output for the PA system and a post EQ XLR out for stage wedges or in-ear monitors. A dedicated tuner out with mute switch lets you quietly tune on-stage. There's even a combination power booster - effects loop to add sizzle and dynamics to the performance and extra presence when soloing!

Compact and easy to use, the Radial PZ-Pre packs in all of the features you need to take your acoustic instrument from home to studio and club to concert.
