Built with a 100% discrete class-A piezo-booster circuit and ultra-quiet preamp front end, the PZ-Pre adapts effortlessly to passive or active pickup systems and delivers clean dynamics, high head-room and minimal noise. With dual instrument inputs, sophisticated EQ and feedback-elimination tools, plus separate balanced direct-out paths for the house and stage monitors, this unit becomes a full signal-control hub for serious acoustic rigs. Whether you’re switching guitars mid-set, blending two pickup sources, or shaping your tone for high-gain live monitors, the PZ-Pre offers the professional utility that boutique-level performers demand.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eTwo independent ¼″ instrument inputs (Input 1 \u0026amp; Input 2) allow quick instrument switching or blending of two pickup systems.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOn-board piezo buffers (PZB) for each input switch the input impedance up to ~10 MΩ—ideal for passive piezo transducers and maintaining natural tone.
