Comes with a power jack now so no power plate is needed.

A fuzz for fuzzes. If you have distortion as your main sound and you can never get enough, try one of these. It magnificently cuts across the grain of fuzz and distortion tones with a searing, sweeping knife-edge tone. At it's heart is a dual frequency-tripler circuit that creates massive crossover distortion for the first time in a guitar pedal. With the input drive set at about 4:00 (that's o'clock), lead guitar tones sweep like a flanger on sustained parts and scream through any amount of distortion. Very strange and upsetting to the other members of the band. An absolutely awful, terrible pedal that people thank me for all the time.

Pedal users in 1997 are very sophisticated. The conventions of in on the right, out on the left, battery connected when input plug is in place, use this pedal before that one for a certain sound, reverse for another, positive ground, negative ground, pedal switching systems... we're living in a 'been there, done that' pedal world. Most every guitarist is familiar with the limitations of puting one fuzz or distortion into another... losing the detail but perhaps gaining that fun "shutdown" effect as one overloads the other, and the "where's my fuzz?" experience of playing a fuzz into a really dirty amp. Limitations. They increase your creativity but hob-gobble your plan.

Z.Vex designed this new distortion generator, Machine, with some different limitations. Like try playing chords through it. Hmmm. But put it in front of any string of fuzz pedals, and try to make it disappear. Machine is actually a dual frequency-tripler circuit that uses crossover distortion for the first time in any pedal, ever. It generates the distortion of the wave in the sloped part of the cycle, instead of the peaks and valleys like all other distorters and fuzzes. In other words, it distorts when your guitar string is in the middle of vibrating, while it's swinging, not as it's turning around. That's the same place where your speaker cone is sort of coasting, between all the way in and all the way out. Where nothing is happening, this pedal happens. With Machine you can leave your favorite distorting pedals on and still add a new element of energetic grind.

Knobs are Drive, which is drive; Limit, which clips the original waveform off at about the same size as the harmonics (if you want); and Volume, which is output level. If the Limit knob is set to the right, the signal remains unclipped.

You'll notice the dynamic response is higher than most pedals. If you put a tremolo pedal set smooth in front of it you'll hear it sweep through it's wild frequency multiplying stages, or if the trem is set for square wave it will jump back and forth between crunchy harmonics. Conversely, you can get ringing harmonic effects using a dynamically freezing pedal in front of it like a compressor. The biggest drawback to this pedal is that of anything in your arsenal, it's the most likely to get you kicked out of the house by your mom, girlfriend, boyfriend, or wife. Or roommate or Dad. Or Grandma. Even your dog. Whine.

Keep in mind that this pedal needs to see a sloped wave in order to do it's thing, so an undistorted guitar signal going into it will allow it to generate the strongest harmonics.

Low on juice use like other Z.Vex pedals, Machine draws about 3 mA. Freaky, huh? Try the Machine run into a fuzz factory for the ultimate in frizzed out thick fuzz!
