The tone control has a lot of range, as well as the sustain

It can break up the signal a bit so the sustain really is invaluable.

I also like the Fab metal pedal if your looking for a cheap distortion that can make your leads sustain and sing.

Great Fuzz and seemingly endless sustain.

Pure fuzz and sustain without having to raise the volume.

Good sustain and tone control

Gives some nice sustain and it "fuzzes" only as much as you want it to.

but it works as it says but

The knobs don't feel cheap and flimsy, though they don't feel as slick as you'd expect from a $100+ pedal.
