Z-TONE Buffer Boost Specifications
Topology
Ultra low noise, high bandwidth and ultra low distortion preamp, buffer and direct box, with boost control and variable gain and input impedance. Transformer-based galvanically isolated balanced output and electronically buffered low impedance unbalanced output. PURE and JFET input stages for total transparency or added harmonics.
