The BigRock Pro high gain distortion can be used into a clean channel or as a preamp into an FX return or power amp. After introducing the popular TightMetal Pro™ distortion pedal in 2013, Amptweaker™ immediately received many requests for a two button Rock distortion. With its included Fat and Smooth switches, the BigRock Pro can get all the familiar tones from our popular. TightRock and FatRock pedals, and many more. Unlike most distortion pedals with boost, the 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. There’s also a Midboost button that works with the output Boost knob, to help solos cut through the mix. Developed while designing the FatRock ‘tweaked’ version of the TightRock, the BigRock Pro has a Smooth Edge switch which cuts the high end sizzle for a warmer edge, and 2 Fat switches for either the normal or Boosted tones to have a thicker attack with a bit more compression, like the FatRock pedal. There’s also a High Gain switch to select between Vintage sounding blues rock or heavier modern rock gain. The added three band EQ allows for much tonal variation, with its PlexEQ button for more traditional stack tone. The standard noise gate from the original TightRock is also included, with 2 separate internal adjustments to help tweak the feel of the gate. Amptweaker pedals are known for effects loops, and this one has 3: a universal loop, another active with the boost, and our popular SideTrak loop which activates when the pedal is OFF, to automatically shut off clean effects. It can be used to add a compressor, chorus or chain of effects that only works when you play clean, or to switch to another distortion pedal to use for an alternate rhythm sound all without having to hit more than one switch it’s like having a built-in A/B box. A green LED alternates with the normal red one to indicate that the loop is active when the pedal is bypassed.
