The Quilter Labs Interbass is a pedal-sized bass preamp, equalizer and DI in one unit. RockBoard's PedalPedia describes it as combining the dynamic processing of the company's Bass Block preamp with its latest direct-out connectivity setup, and says it is "loaded with powerful features for going direct to PA and recording consoles"1. For a bass player, that means one pedal that shapes tone, matches the input to the instrument, and feeds a front-of-house desk or an audio interface without a separate DI box. It sits in the wider field of preamp pedals and bass pedals.
Circuit and signal path
The Interbass is an analog pedal. Quilter's listing gives its circuit type as analog and describes the pedal-sized Interbass as combining "the unmatched dynamic processing of the Bass Block preamp" with the company's direct-out connectivity1. In other words, the core of the pedal is the same signal path Quilter built for its Bass Block preamp, repackaged as a foot pedal and paired with the outputs needed to send the signal straight to a mixing desk or recording console.
Controls and input matching
The listing identifies an Active/Passive switch that optimizes input level1. Basses with onboard preamps (active) and those without (passive) deliver very different signal levels, and this switch sets the Interbass input to suit whichever instrument is plugged in.

Power requirements
The Interbass runs on 24V DC, center negative, and draws 3000mA1. That current draw is far beyond what a typical pedalboard power output supplies, so it needs its own dedicated supply.
The Interbass needs a 24V DC, center-negative supply rated for its 3000mA draw1. It should not be daisy-chained from a standard pedalboard power brick output.
Going direct
Quilter positions the direct-out connectivity as a headline feature, describing the pedal as built for going direct to PA and recording consoles1. Players who run the pedal on a board and hand a balanced signal to the sound engineer, or record straight into an interface, can use the Interbass as the last stop in the chain.
What Quilter says about the pedal in its own words:
"loaded with powerful features for going direct to PA and recording consoles"

Questions
Is the Quilter Interbass analog or digital?
The Interbass is an analog circuit. Quilter's product listing gives its circuit type as analog, and it combines the Bass Block preamp signal path with Quilter's direct-out connectivity setup in a pedal-sized unit.
What does the Active/Passive switch do on the Interbass?
The Active/Passive switch optimizes the input level for the bass you plug into it. Active basses, which have onboard preamps, and passive basses put out signals at different levels, and the switch matches the Interbass input to either kind.
What power supply does the Quilter Interbass need?
The Interbass runs on 24V DC, center negative, and draws 3000mA. That is a higher voltage and a much higher current draw than a standard 9V pedal supply output, so it needs its own suitable supply rather than a typical pedalboard daisy chain.
Can the Interbass go direct to a PA or recording console?
Yes. Quilter describes the Interbass as loaded with powerful features for going direct to PA and recording consoles, and it combines the Bass Block signal path with the company's latest direct-out connectivity setup.
Is the Interbass based on the Bass Block preamp?
Yes. Quilter says the pedal-sized Interbass combines the dynamic processing of the Bass Block preamp with its latest direct-out connectivity, combining the best features of the Bass Block signal path in a pedal.
Where can I find the Quilter Interbass manual?
The English manual is available as a PDF from Quilter, linked from the product's listing on RockBoard's PedalPedia.
