- Ground lift switch eliminates buzz & hum
- Designed and made in Italy
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.
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.
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.
Use Z-TONE Buffer Boost to supercharge your sound. The included Boost circuit offers adjustable gain to increase volume & drive, hitting your amp or pedals harder.
Long cable runs, low-impedance stomps and complex routing can degrade your guitar’s signal, causing muffled, bassy or lifeless tone. To ensure your signal always stays crystal-clear, Z-TONE Buffer Boost offers a transparent output buffer so you always sound your best.
And Z-TONE Buffer Boost offers a true bypass circuit, so it’s completely transparent when not in use.
In addition to the “Link” amp & pedal output, Z-TONE Buffer Boost offers a balanced XLR output to connect to mixers & PAs. Skip the amp and perform direct, or mix clean and processed signals to create even more tonal options.
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.
