A set it and forget it distortion rock box. Hwy-77 is designed to simply feed thick and meaty distortion into your amp. Simple in function, Level and Gain controls are sensitive and accentuate what playing style. Bright switch provides for more variation and forces the tone to tighten up on low end rock. Decadent response to humbuckers and plenty of punch for single coils. Luxurious headroom for recording and driving other pedals and amps. Voiced openly and responds well to bass. The Heavy Electronics Voltage starve circuit (adjusted internally) decreases clipping threshold and adds compression. Adjustable LED brightness to conserve battery life if necessary. Bottom line, this pedal is about tone. The Hwy-77 is highly responsive to both level and gain settings and cleans up with your guitar volume knob. Excellent response at Low gain settings too.
