This is a "two in one" pedal, acting as an amplifier simulator and a clean boost pedal. Three switches (mic, mod, and amp) offer 27 different combinations of microphone position, amplifier characteristics and saturation ("drive"). Five potentiometers let you control drive, level and complete equalization (low, mid and high frequencies). An extra potentiometer lets you set booster's gain. Booster is independent: it can be used either with clean sound or with the effect.
Controls: DRIVE, LOW, MID, HIGH, LEVEL, MIC (3-pos.), MOD (3-pos.), AMP (3-pos.), BOOST
