This ultra-low noise, all-analog tone shaping tool works equally well in front of your amplifier or as a preamp/direct box via its balanced XLR output. High-quality Burr-Brown Op-Amps and a straightforward yet versatile control panel deliver rich and dynamic tones with ample headroom and maximum tweakability.  From warm, vintage tones to modern low-end thump, ZIO is the first and final step in elevating your bass to its rightful place in the mix.\n \nTotal Tone Control\nThe ZIO Analog Bass Preamp + DI features a perfectly executed and  intuitive set of tone controls to take your bass sound wherever it needs to go.  When used in tandem, the BASS and FOCUS knobs offer tremendous depth and power.  The BASS knob provides colossal low-end boost at around 100Hz, while also gently reducing muddy low-mids to retain clarity. The FOCUS knob sweeps the cut-off point of a high-pass filter to tame excessive sub bass and low bass frequencies, providing extra headroom for a concise and punchy sound. Boost or cut the highs with the TREBLE knob to either enhance articulation without adding harshness, or smooth attack transients for a softer approach. The OUTPUT knob offers up to +16db of overall boost above unity gain or up to -6db of cut. Whatever your bass model or musical genre, ZIO offers tremendous tonal range.\nThe Official Source Audio ZIO Analog Bass Preamp + DI Demo Video\n \nMore Epic ZIO Demos\nNathan Navarro\n \nBass the World\n \nThe Bass Channel\n \nPatrick Hunter\n \nNatural DriveThe GRIT toggle captures the magic of transformer-style breakup, the tone that occurs when a vintage tube amp gets pushed to overdrive.
