It has an old school metal vibe to it. Thick and dynamic, it's really great for chunky rhythm playing. It will push beyond that '80s sound, into very modern territories. With a down-tuned guitar at full crank with the red mode engaged, you can get into extreme and aggressive metal. By dialling the gain right back, adding a little midrange, and switching the aggression mode off, you can get into big, open sounding classic rock tones - This is the '80s rock multi-tool!
Each one of the three tone pots has an extensive range that can really affect the 'size' of the sound, as well as the tone. With the bass down it can sound like you are playing a raunchy small amp. But when you increase it, a sense of weight starts to bloom from your amp - it's a little like adding a 4 x 12 cabinet.
The midrange is expressive, forward, and large at full tilt. When scooping, the pedal compensates by adding extra harmonic content to the bass and treble, and this is where things get aggressive and tight. Then furthering that sound, the treble can add a fierce bite but that sometimes needs a little taming. Turned all the way to the right, the treble is upfront and intense. If you are taking sounds to the extreme or just want to access a gigantic range of sounds, then you can't go wrong here.
There are two other modes which shape and alter the gain: the red and blue position. The blue position has a touch more gain with a tighter midrange, adding a more aggressive quality to the trebles. On the red channel, you get an absurd increase in gain that leads to a different quality to the mids and top end. It's thick and heavy, lending itself to chunky leads with strong overtones - making sure you stand out, in any mix.
