This fuzz has 4 knobs: bass, trebble, level and sustain.
The bass and treble can adjust bass and treble (no joke) but in a way different from other pedals, a tone much more effectively. This is the system Baxandall, which removes the treble beyond a certain point, or to add with mediums that are stable. Same for low, we can remove or withdraw without affecting the mids.
It has an input, output and power input. There is also a compartment for 9V battery, it will, however, remove the pedal for it.
Usage is very simple.
The sustain is very linear and stable throughout its course, one little therefore increase the amount of fuzz.
The bass and trebble system works perfectly.
This pedal is a killer for any big sound typical stoner rock, desert rock ... etc.. The approach makes it easy to sustain groups like fu manchu or electric wizard at the end of the race.
In fact, despite the seemingly simple or simplistic of this pedal, the sound palette we can draw is huge.
In fact, the bass and trebble knob are very effective produissant extremely different tones depending on the combination of the two. In addition, the pedal is very responsive to volume / tone of the guitar, which creates even more combinations to define a "beach" exact frequencies where the fuzz will lie, which is extremely convenient when playing group for the fuzz does not mask all other intruments or otherwise be drowned out by the other intruders.
You can also put a microphone eg low volume for a very low fuzz (this will be about crunchy) to move to the next heavier.
It responds very well to the nuances of game too, which is a big plus for me.
After that it should be adept at high gain fuzz big muff typed.
This is not a pedal I advise not fans of doom, it still has a large dynamic ranges away fuzz sound delivered by some groups.
I use it for 1 month now.
I love the precision of tone / fuzz amount possible to obtain many different sounds.
After the fuzz is very typical, it is not really a very versatile pedal, rather it is made for heavy riffs and slower than the jimi hendrix example (even if by fiddling the settings you can always make a good sound )
