From Mad Professor:

BJF design dynamic bass overdrive.

Mad Professor BlueBerry Bass Overdrive (BBBOD) is a high quality dynamic overdrive pedal for electric bass.

It was designed to get light to medium overdrive, reminiscent of vintage tube bass amplifiers.

With the Drive control, you can get natural dynamically controlled overdrive like on those old tube bass amplifiers, or more compressed thick distortion.

At lower drive settings the BBBOD distorts more the harder you strike the strings, and there is no definite clipping point, but rather different shades of distortion as the amplitude changes. Higher settings will give more compressed sounds.

With the clever Nature adjustment one can adjust the tone, and also control what register distorts. From really big and fat with low register distortion to cutting upper midrage solo bass tone.

There is enough volume to use the pedal also as a booster.

While mainly designed for bass guitar, the BBBO can also be used with other instruments for low, dynamically controlled distortion.

The echo signal has a tuned filtering to allow extreme settings without interference. The delay is specially designed to work well with distorted tone, as this is the most critical application, where delays often fail. You can use the pedal before or after distortion. As such, it will work exceptionally well on clean sounds where requirements are less stringent, especially in terms of echo bandwidth and repeat formation.

The delay tone has been carefully tuned with lot of attention to the first critical reflection and how the repeats decay. Deep Blue Delay is kept small (Width x Length x Height :69mm x 111mm x 50mm including jacks and knobs) containing just the basic delay features; Delay Time, Delay Level and Repeat controls. It was designed to work as an ambience delay; like that of a vintage tape echo and the repeat formation was specifically designed to allow easy setting and less critical setting of delay time. With delay times higher than 120ms, the delay time is sometimes set on the beat or on a multiple of the beat. Deep blue handles this by not giving full range repeats, but a tuned response that don’t need to be on the beat to sound good.

Why digital? Isn't Analog better for a solid-state solution?

Well, in many ways, the delay medium is less critical and it could be an oil-drum, tape, metal-thread, analog BBD or digital, but the final sound is always set by the limitations of the delay medium and the peripheral circuitry needed to make either work. We chose Digital construction to make it compact, stable, with reasonable delay time and virtually service free, where the limitations of the circuit would be less critical. As an outcome, you can set the peripheral circuitry with desired bandwidth and distortion levels with less consideration on the exact limits of the delay medium, while of course always pushing the limits, as with anything musical.

A similar circuit in analog form would be excessively more expensive to make. For the same performance, it would require three to four of the best BBD chips now only available as vintage parts and the size of the pedal would have to be about three times the current size.
VOLUME : controls output DRIVE: sets the amount of distortion and sustain, as well as the type of distortion. Lower settings give dynamically controlled overdrive, the unit distorts more the harder you strike the strings and there is no definite clipping point, but rather different shades of distortion as the amplitude changes. Higher settings will give more compressed sounds. A good starting point with most basses is fully CCW, turn the knob until you find the overdrive level that suits your playing. Lower settings are good for old school tube amplifier tone, while higher settings gives denser distortion. NATURE: is a tonecontrol for filtering and to control what register distorts. Turning CCW gives more lowend and also distortion in the lower registers. Turning CW gives an emphasis in the upper midrange for more protruding solo bass tone.
