ZIO Analog Bass Preamp + DI

The Source Audio ZIO Analog Bass Preamp + DI is an analog preamp and direct injection (DI) pedal specifically designed for bass instruments. This bass preamp pedal includes EQ controls for bass, treble, and focus, along with tone-shaping toggles for grit and scoop. Equipped with Burr-Brown op-amps for high headroom and low noise, the pedal supports three independent outputs: ¼” instrument output, balanced XLR DI output with ground lift, and a dedicated headphone output. The output gain ranges from -6dB to +16dB above unity, and a side-mounted gain control adjusts the grit switch’s overdrive character. The bass control boosts around 100Hz, while the focus knob acts as a variable high-pass filter. The treble knob adjusts higher frequencies for articulation or smoothing. The GRIT toggle adds transformer-style breakup, while SCOOP applies a midrange cut for clarity. **Features:** - Analog bass preamp pedal with DI and headphone outputs - Dedicated ¼" output, balanced XLR output with ground lift, and headphone jack - EQ controls for bass (100Hz), treble, and focus (variable high-pass filter) - Grit toggle for natural analog-style overdrive; side gain control - Scoop toggle for midrange reduction (“Pultec Trick” inspired) - Compatible with bass instruments
