Z-TONE(TM) DI is a premium active direct box packed with unique tone-shaping features. Whether you want more flexible routing on-stage or superior tone shaping in the studio, Z-TONE DI borrows the input circuits from our award-winning AXE I/O interface to let you do a whole lot more, and sound better doing it. Z-TONE DI preserves the natural tone of your instrument with exceptional headroom and transient response, and gives you powerful sound-shaping options. First, an active/passive pickup switch with adjustable input gain lets you easily dial in exactly the right input level for your axe. Next, choose from PURE and JFET input channels to give you more tonal options. PURE is a completely transparent and colorless preamp that won't color your sound, while JFET offers a Class A JFET to add subtle midrange focus and warmth. Z-TONE DI also offers our patent-pending variable impedance control, letting you dial in impedance from 1 MOhm to 2.2 kOhms to shape your sound In unique ways. 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.
