Description
An all-analogue Preamp and DI for Bass Guitar
The ZIO Analog Bass Preamp + DI is an ultra-low noise, all-analogue preamp and DI for use with the bass guitar. The pedal offers maximum headroom and a simple but flexible set of tone-shaping controls. ZIO Bass can be used as a direct input using the balanced XLR output for connection to a mixer or audio interface as well as with headphones through its dedicated headphone jack.
Controls
- OUTPUT: The OUTPUT knob offers +12db of additional boost plus a significant amount of cut.
- BASS & FOCUS: The BASS and FOCUS control work best in tandem – use the BASS knob to increase low-end output and the FOCUS knob (which adjusts the cut-off point of a high-pass filter) to eliminate excessive lows and create added punch.
- TREBLE: The TREBLE knob boosts or cuts the high frequencies, providing enhanced articulation without adding harshness.
- GRIT: The GRIT toggle enables a mild distortion to mimic the transformer-style breakup from high-end bass amps. GRIT mode’s gain level can be adjusted for more or less distortion with the GAIN control located on the side of the pedal.
- SCOOP: The SCOOP toggle engages a special midrange cut to clean up “muddy” mid-range frequencies.
The pedal has three outputs that can be used individually or simultaneously. The OUTPUT jack connects to an amplifier or pedalboard. The DIRECT OUT is a balanced XLR output that sounds great running into a mixer or audio interface for recording or live sound applications. The HEADPHONE jack features a high dynamic range, a low-noise amplifier that is capable of driving low impedance studio headphones.
