The DigiTech Screamin' Blues is an analog overdrive and distortion pedal designed for guitarists who want a drive that responds to their playing. RockBoard's PedalPedia describes it this way: play lightly and you get a subtle overdrive, dial up the gain and dig in to get rich harmonics and killer sustain1. It sits in the territory shared by overdrive pedals and distortion pedals, covering both roles in one box.
Separate low and high EQ
The Screamin' Blues' distinguishing feature is its tone shaping. Instead of the "one knob does it all" tone adjustment found on many drives, it gives you separate low and high EQ adjustments to dial in the sound1. In practice that means you can add body to a thin-sounding amp or tame harshness on top without dragging the other end of the spectrum with it, which a single tone knob cannot do.
Power and practicalities
The pedal runs on a 9V DC, center negative supply and draws 23mA1. That is a modest draw by modern standards, but it is worth knowing when budgeting the capacity of a shared supply or daisy chain.
The Screamin' Blues draws 23 mA2, and DigiTech markets it as one "rough rugged designed stomp box that gives you more output and tonal options than the other guys!"2. Factor that current draw into how you power a board.
RockBoard's PedalPedia describes the enclosure as one rough, rugged designed stomp box that gives more output and tonal options than the competition1.
Where it sits among DigiTech drives
The Screamin' Blues sits in DigiTech's line of overdrive pedals. It is built as a "rough rugged designed stomp box that gives you more output and tonal options than the other guys!"3, and it draws 23 mA3, which is worth bearing in mind when sharing power with other pedals on a board.

Questions
Is the DigiTech Screamin' Blues analog or digital?
The Screamin' Blues is an analog pedal. Its circuit type is listed as analog, meaning the signal is shaped by analog components rather than converted to digital. That matters for players who build their chain around analog drives or want the pedal to sit naturally in front of a tube amp.
What power supply does the Screamin' Blues need?
The Screamin' Blues runs on a 9V DC supply with a center negative plug, the same standard used by most compact pedals. It draws 23mA of current, so a standard supply with enough spare current handles it, but it is worth confirming your supply's output before adding it to a daisy chain.
Is the Screamin' Blues an overdrive or a distortion?
It is both. DigiTech designed it as an Overdrive/Distortion pedal: played lightly it produces a subtle overdrive, and with the gain turned up it delivers rich harmonics and sustain. It suits players who want one pedal that covers both roles depending on picking strength and settings.
Where can I find the Screamin' Blues manual?
An English-language user manual for the Screamin' Blues is available as a PDF, linked from the RockBoard PedalPedia entry for the pedal. The manual covers the pedal's controls and operation in detail.
