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 The ideal front-end Z-TONE Buffer Boost offers a high-quality instrument preamp with exceptionally low noise and wide frequency response, and multiple circuit topologies to adapt to any type of guitar, pick-up and style.

Passive Pick your pickup: PASSIVE: designed to accommodate everything from low-output vintage pickups to hotter modern humbuckers with ultra-low noise and extended frequency response.

ACTIVE: bypasses unnecessary gain stages when using active pick-ups, to keep your signal path as direct, transparent and clean as possible.

Pure Choose your channel: PURE: a completely transparent and ultra-accurate preamp  circuit that won’t color  your sound in any way.

JFET: a Class A JFET input buffer for subtle harmonic  enhancement, midrange focus and warmth.

Tone and feel like you’ve never heard Guitar pickups can dramatically change their character depending on impedance - many amps offer a load of 1 MOhms, while pedals can run much lower.  That’s why the tone and responsiveness of your guitar can change when plugging into different gear.

Z-TONE Buffer Boost gives you the same variable impedance control as our groundbreaking  AXE I/O audio interface, from 1 MOhm to 2.2 kOhms. At the maximum impedance, you’ll find your sound tighter, sharper and more precise. Increase the load and the sound becomes thicker and more bold.  Z-Tone You can use this control to coax a wider range of sounds from a single guitar, experiment with how the rest of your rig reacts to these changes, or dial in exactly the right vibe regardless of what comes next in your chain.
