This is a Marshall-style pedal. The gain is broad and you can push sounds by boosting the amp or create deep distortion by using this pedal. You can put the gain on full without effecting the quality of the sound and produce an excellent distortion. Thanks to the toggle switch, you can choose between TIGHT and DEEP. TIGHT matches well with rhythmical play or humbucker pick up, whereas DEEP boosts the medium to low range and is perfect for guitar solos and single coil guitars.
