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.
