Bass players have never heard such shocking subs from a pedal before. This fuzz will give you the classic 60's/70's artillery-fire tone that you can never get with a regular fuzz on bass. The bottom end stays solid when you kick it in... be careful to remove beer bottles from the amp before you turn it on. A muff-like eq knob lets you tune in exactly how much high end goes through your DI box and the pinch knob mutes any hiss and noise when you stop playing. Guitarists love it too, but once the bass player touches it, it's gone.
...a furry beast, and as you can see, not completely extinct.
A BIG-BONED BEHEMOTH...
Sensitive and touchy, this fuzz has tremendous bottom end a beautiful harmonic structure.
Taming the beast...
The harmonic structure can be altered using the "pinch" knob. This is not a tone control, per se; it actually adjusts the pulse width of the waveform.
In the leftmost position, the wave shape is quite symmetrical which produces a smooth creamy sound.
Turning it clockwise narrows the wave shape into pulses, making the tone reedier and brassier. This also introduces an unusually smooth 'gating' action, which gives you an absolutely eerie silence between notes.
At all settings you will notice that low frequency pressure is preserved. This circuit has a frequency response that continues several octaves below audibility.
Starting 7/98 there is now an EQ knob added for a total of 4 knobs, at a slightly higher price.
The "wool" knob adjusts the amount of fur around the note. The "output" knob is designed for smooth repeatable level settings.
In our continuing effort to be friendly towards the earth, the universe and it's inhabitants; no animals were harmed during the making of this pedal.
Oh, and the circuit ( designed by Chuck Zwicky ) draws less than one-half of a milliampere ( 0.0004 amps, typical ). That is one-hundredth the current consumption of most 'commercial' pedals
Now with power jack and LED!
