This is my first fuzz pedal.
So, I didn't quite know what to expect, when plugging my guitar in to it.
I had heard fuzz before on records and at concerts, so I was aware of what sounds a fuzz pedal should make.
After playing around with the knobs and switches I was surprised that a good tone is easily achieved.
The VOLUME knob, does exactly as you'd expect, it increases or decreases the overall output of the pedal.
The TONE knob, determine which frequencies are more prominent, anti-clockwise, more bass, clockwise, more treble.
The SUSTAIN knob, determines how much adjusts how much the pedal, sustains and how much it distorts, both increase by turning the know clockwise.
The TONE switch, in the off position, bypasses the tone circuit, this gives you a full bore sound, make sure your amp isn't cranked before flipping this switch, it gets loud. I personally prefer to have the tone circuit activated, I feel it gives me more control of my sound.
The WICKER switch, probably best described as a BRIGHT switch. This switch when activated, opens up the high frequencies. Allowing you to cut through the rest of your band, especially the bass player.
The tonal possibilities are vast with this pedal. Well worth the extra money, considering, it is the standard pedal with a couple very good extras.
