4 knobs:
-1: Level (Output Level / v)
-2: Tone (Tone Distortion)
-3: Gain (amount of distortion effect)
-4: MORPH (specialty Digitech: rotary switch allowing you to travel between the four tones of rock characteristics: ProCo Rat (Jeff Beck), BOSS DS-1 (Kurt Cobain) or Dallas Arbiter Fuzz Face (Jimi Hendrix).

Another special touch of Digitech: 2 outputs. So you can leave your stereo sound. Another twist is also very useful for your sound: the second output allows for a half-stack sound if you go through a mixer or a home stereo!

Power supply 9-volt battery or Sector

Perfect for a simple distortion pedal ... it has all the classics in a box!

UTILIZATION

Terribly simple! Even your cousin for six years (or less) could use it!
Turn the knob and you got your sound good c! And not just any sound more ... one of the greatest!

SOUND QUALITY

Then I can tell you ke kan I plug my Start and I put pr ke sound like a fuzz face, c good, I ring (a very very very nearly) like Hendrix! And with that I can find any sound of rock! from oldest to most recent, this pedal has all the sonic palette for you!
No complaints!

OVERALL OPINION

this pedal really impeccable ...
I put 9 because nothing and no one is perfect, but I am tempted to put 10!
