Source Audio Zio Analog Bass Preamp

Source Audio Zio Analog Bass Preamp  is an ultra-low noise, all-analog preamp and DI for bass guitar with loads of headroom. The pedal has a simple but flexible set of tone shaping controls. It 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.

The OUTPUT knob offers +12db of additional boost plus a significant amount of cut. The BASS and FOCUS controls 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 eliminated excessive lows and create added punch. The TREBLE knob boosts or cuts the high frequencies, providing enhanced articulation without adding harshness.

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. The SCOOP toggle engages a special midrange cut to clean up “muddy” mid-range frequencies. The SCOOP profile is based on the “Pultec Trick” – a setting commonly used with vintage Pultec Equalizers to add clarity.

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, low-noise amplifier that is capable of driving low impedance studio headphones.
