BigRock Pro includes 2 Boost knobs, one before and one after the distortion.....so it’s easy to boost the gain AND volume, for the perfect solo tone! Patch your favorite delay into the Boost Effects Loop, and you’ve got onestomp control of your rock rhythm and lead. Added switches on this pedal allow it to get tones from both our popular TightRock and FatRock distortion pedals. These include the Smooth Edge switch which cuts the high end sizzle for a warmer edge, and 2 Fat switches that allow either the normal or Boosted tones to have a thicker attack with a bit more compression. The added three band EQ allows for much tonal variation, with its PlexEQ button for a more traditional stack tone. Our standard noise gate from the original TightRock is also included, which tracks the gain knob and has internal adjustments. Amptweaker pedals are known for effects loops, and this one has 3: a universal loop, the Boost loop, and our popular SideTrak loop which activates when the pedal is OFF, to automatically switch in/out clean effects.
