From Mythos: Inspired by a legend The Chupacabra takes its tonal inspiration from the biggest little band from Texas. Utilizing a CMOS Hex chip the Chupacabra has huge amount of output and gain range for a versatile drive that melds perfectly with you guitar setup. The gain ranges from tweed push to "your amp about to die" for some pseudo fuzz-like tones. Tonally, the voicing is pretty flat with a slight bump to lows and highs without being too drastic. Simplicity is Key The Chupacabra CMOS Overdrive is made for those that love using their guitar controls. It's responsive and dynamic and doesn't get in your way. Like all other Mythos Pedals we use high quality panel mount In, Out and DC jacks so your pedal will be reliable on the road for years to come. Chupacabra Controls Volume - Adjusts the output. Gain - Adjust gain levels.
