The RangeMaster is modeled after the The Dallas RangeMaster Treble Booster© (*). The Dallas RangeMaster Treble Booster© (*) was an effect unit made for guitarists in the 1960’s. It was originally made for two things: to increase the signal strength of the guitar going into the amplifier, and to boost the higher notes. With the original pedal only having one knob to set the amount of boost, this pedal also has a mix knob to set the dry/wet mix.
