The Joyo Voodoo Octave is a very good buy if your curious about octave fuzz pedals. It can be used as a straight fuzz pedal, or you can hit the octave switch and get sounds from piercing to synth like depending on the settings. It also has LED's to let you know if it's on fuzz, octave or both.
For a solid year and 4 months I have had this either on my touring board or IN my gig bag ready for the hotel room. It was a Christmas present "stocking stuffer" that my wife ordered on Amazon kind of last minute and I absolutely love it. The ability to go from straight up "RATISH" distortion to a very cool lower gain, mid scooped (thanks to the mid scooping switch on it) Octave up weirdo sound is awesome. You have the ability to turn the octave effect on and off while the gain is turned on so getting on planet Smashing Pumpkins isn't hard. BUY IT. It's worth its penny in the pocket price tag
Got this off amazon not expecting much but i was amazed after plugging her into my amp.With this fuzz box i could copy sounds of bands like The Rolling Stones,The Stooges,and even The Beatles.
