Part of Russian firm's Yerasov 'Insect' series, said to be of boutique quality, and each named after a particular bug, the pedal features an embossed graphic of said creature, which looks a bit vicious. That's appropriate, really, as the sound is more than capable of having some bite to it.
What you are buying into is a distortion pedal with the usual volume and gain knobs, but also three-band EQ with separate treble, middle and bass controls.
The range on tap runs from a practical gritty boost that can take your amp up that extra notch, through to the balls-out distortion of a cranked stack.
If you want to retain your tone or give it a subtle tweak, the EQ ranges have been chosen sensibly to complement each other, like on an amp, while still being capable of more radical stuff such as scooping out some midrange and combining treble and mid boosts to project solos through a full-band mix.
A hard-rocking distortion unit that will let you set the tone.
