The SOUND knob affects several parameters at once. For fat and "clean" sounds, the control should be located on the left. In the middle you will find "crunch" sounds with cutting attack - and on the right you will be welcomed to the "high-gain" sounds. So you can even find sounds that are not present in the original amp. If you turn the SOUND control knob to the "DRIVE" position, for example, you get the high-gain settings that with the original you only obtain by using an additional booster pedal. If you then turn the knob back to the "CLEAN" position, you get a "bright" sound with a wider frequency range than an original AC. Flexibility enough-and you only have to turn one control.

You can connect a guitar, another musical instrument or another effect to the input. This connector doubles as an on/off switch. Connecting a jack to the input turns the pedal on. Unplug the cable again to turn the pedal off.

The pedal is also equipped with tone controls: BASS for the low frequencies and TREBLE for the highs. The LEVEL control determines how loud the effect goes when you turn it on.
