Preamp/DI pedal with advanced tone shaping Guitar & bass pedalboards are all about exploring new tones & textures, creating a wide range of sound for your instrument. Z-TONE® Buffer Boost takes your live rig to a new level, letting you shape the sound of your instrument with the input circuits from our award-winning AXE I/O interface. Key Features Active/Passive pickup selector PURE channel for transparent sound JFET channel adds warmth & harmonics Z-TONE variable impedance control creates a wide range of tones Buffers signal for longer pedalboards & cable runs Boost circuit adds volume & drive Alternate outs for mixers & PAs Ground lift switch eliminates buzz & hum Designed and made in Italy 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. Audio specs I/O Gain: Unitary, from 1/4” input JACK to both 1/4” and XLR outputs when GAIN is at 0dB and Z-TONE at the SHARP position.
