The Controls
BASS & TREBLE
Bass/treble controls. Add bass for more punch or roll off a bit for a tighter sound, especially on big
cabinets. Add treble to cut through a dense mix or compensate for signal lost in long cables. For a
softer tone, try reducing the treble.
GAIN
Controls the amount of gain. This is a clean booster pedal, but a high gain setting gives a natural
break-up as on a cranked amp.
LEVEL
Sets the overall level.
