Level Knob - DigiTech SCREAMINBLUES Manual

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.
