The English created the classic timbres that made the history of Rock 'n' Roll in the 60's and 70's. We put this sound in the GNI Shred Pro. Not only a drive until, it is also a versatile independent booster that includes lots of controls to make this a very complete vintage solution.


  • DRIVE: This adjusts the amount of distortion ("Drive") of the pedal.
  • BASS, MID, and TREBLE: These knobs adjust, respectively, low, medium and high frequencies.
  • LEVEL: Output level.
  • BOOST: This adjusts the intensity of the independent booster, which is turned on pressing the respective pedal.
  • MOD SWITCH: This pedal reproduces three different classical timbres of the 60's and 70's. Positions are:
    1. Results in a more "present" sound.
    2. Same sound, with a little less brightness.
    3. Classical timbre, with attenuated medium frequencies.
  • EFFECT LED: Indicates when effect is on.
  • BOOSTER LED: Indicates when booster is active. Its color also changes according to booster's intensity setting.
