The Screamin’ Blues Overdrive / Distortion is designed for guitarists
who need a pedal that responds to playing dynamics. Blues players in
particular will love how the Screamin’ Blues gives them total control of
their tone. Playing lightly gives you a mild overdrive, but dialing up the
gain and digging in hard will make the Screamin’ Blues sing with ultra-
rich harmonics and sustain.
1. Level Knob
Controls the effect output level. Turn this knob clockwise to increase
the output level, and counter-clockwise to decrease output level.
When using an amplifier with moderate gain, the Level knob can be
turned up to drive the input harder and increase your amp's own
natural distortion. Be sure to turn down the Gain knob when using it in
this manner.
2. Low Knob
Controls the boost or cut of low frequencies. Turn this knob clockwise
to increase the low frequency content, and counter-clockwise to
decrease the low frequency content.

3.AC Adapter Jack
Connect a DigiTech PS200R power supply to this jack. Use the proper
supply for your area’s Mains line voltage.
4. High Knob
Controls the boost or cut of high frequencies. Turn this knob clockwise
to increase the high frequency content, and counter-clockwise to
decrease the high frequency content.
5. Gain Knob
Controls the amount of distortion. Turn this knob clockwise to increase
the amount of distortion, and counter-clockwise to decrease the amount
of distortion.
6. Input Jack
Connect your instrument to this jack. Connecting a guitar cable to this
jack engages battery power even though the Indicator LED may not be
lit. To prolong battery life, disconnect all cables from the pedal when not
in use.

7. Pedal Release Pins
These two pins are spring-loaded hinges that hold the pedal in place.
Push these pins in to release the pedal from the chassis exposing the
battery compartment. (See battery replacement diagram.)
8. Pedal
Press the pedal to turn the effect on and off.
9. Out 1(Amp) Jack
Connect this output to your guitar amplifier.
10. Indicator LED
This LED indicates when the effect is turned on. If the LED becomes
dim or does not light when the cables are connected, the battery needs
to be replaced.
11. Out 2 (Mixer) Jack
This output features DigiTech’s speaker cabinet compensation, that lets
you run the pedal directly into a mixer or recorder input without having
to use a guitar amplifier.

Connections
The Screamin’ Blues has a single input (INPUT) and a pair of outputs
(AMP and MIXER). The two outputs give you the following options:
running into a guitar amplifier, running directly to a mixing console or
recording device, or both. The MIXER output uses DigiTech’s speaker
cabinet compensation for an authentic guitar amplifier sound without
using an amp.
Follow these setup directions before use:
1.Turn the volume down on the amplifier/mixer you are connecting to.
2. Connect the pedal output to the amplifier/mixer input.
3. Connect the guitar to the pedal input.
4. Connect the power supply to the pedal (optional).
5.Turn the level control on the pedal to the minimum position.
6.Turn up your amplifier/mixer level to the desired listening level.
7.Turn on the pedal by pressing the pedal switch and gradually turn up
the level to the desired listening level.

Battery Replacement
1. Using the tip of a 1/4” guitar cable, push one of the release pins in on
either side of the pedal, and remove the pedal from the pedal chassis.
2. Remove the battery from the battery compartment and disconnect
the battery cable.
3. Connect a new battery to the battery cable and put it back in the
battery compartment. Make sure the battery cable does not interfere
with the spring or pedal switch arm.
4. Place one hole of the pedal over its corresponding pin.
5. Push the opposite pin in and lower the other side of the pedal into
place over the depressed pin. Release the pin. When the pedal is
properly fastened, both released pins are flush with the outer side of
the pedal.
