Beskrivelse
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. Change the tone & feel of your guitar or bass, buffer your tone to survive even the biggest pedalboard, kick in the boost and supercharge all your existing gear with a powerful new front-end.
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.
