Z-TONE Buffer Boost

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
