A handmade germanium booster with range control based on the 1966 Dallas Range Master Treble Booster circuit. Known to be used to sculpt the tones of many UK guitarists in the '60 and '70ies as Iommi, Bolan, Clapton, Gallagher, May or Judas in his early works
The pedal boost the signal, emphasizing medium/high frequencies adding a raw sound but with a softness similar to the achieved by leaving the wah in a fixed position and cleans well with guitar's volume. With the Range control the spectrum of frequencies is expanded to find the desired tone that suits your equipment
Also there's an option without the Range control
