Take your live rig to a new level! Z-TONE Buffer Boost offers a high-quality instrument preamp with powerful tone shaping options, switchable boost for extra drive and volume, and buffers your signal so it doesn’t degrade over long cable runs or big pedalboards. It’s the ideal leadoff hitter for your pedalboard or amp rig. Z-TONE Buffer Boost offers 3 different input circuits - 3 different options to adapt to any type of guitar, pick-up and style. PURE: a completely transparent and ultra-accurate instrument preamp that won’t color your sound in any way. JFET: a Class A JFET input buffer to add subtle harmonic enhancement. A slight midrange focus adds warmth, giving you more tonal options from the same instrument. ACTIVE: bypasses unnecessary gain stages when using active pick-ups, to keep your signal path as direct, transparent and clean as possible. Z-TONE Buffer Boost also includes IK's patent-pending variable impedance control, letting you change impedance to shape your sound in unique ways. At max 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 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 runs on a standard 9V battery or 9V pedal power supply, so it’s easy to drop onto your existing pedalboard.
