This one is a "set it and forget it" distortion rock box. The Hwy-77 is designed to simply feed thick and meaty IC distortion into your amp.Simple in function, Level and Gain controls are sensitive and accentuate playing style. No "die-off" as gain is decreased. Rather, lower level gain tone is open and warm. Decadent response to humbuckers and plenty of punch for single coils. Luxurious headroom to aid in recording and driving other pedals and amps.
