The volume knob gives you more than enough headroom to easily drive you amp into natural breakup but the range knob is where the magic is found. When turned to the left 50% you have Rangemaster/Treble Booster tones and to the right 50% you have full range boost tones in the ranks of a LPB-1 power booster. The placement of this pedal can yield vastly different results. When ran after your overdrive or fuzz it projects exactly what it hears and sends it soaring above the mix. If you run it before your dirt boxes you can force them into rich harmonic saturation that will cause a permanent smile on your face. Either way you choose, the result is a booster that does its job so well you may never turn it off.
