I got this as an "alternative" distortion pedal, but it's very hard to get a great sound "by itself" as a distortion generator. The distortion is nicely saturated, but it sounds kinda fizzy. The Hi and Low Boost modes are very harsh sounding, particularly the Hi Boost, which can probably break glass along with ear drums.
However, I have indeed found a great use for this as a boost/overdrive pedal. It contrasts my Ibanez TubeScreamer in a great way in that the TS cuts lows and boosts mids, while the Mooer Blade does the opposite and boosts lows (and highs) while scooping the mids quite a bit. This thing genuinely sounds terrific boosting my Marshall amp into full-on saturation.
As a distortion pedal, the Mooer Blade is lacking. But as a booster pedal, the Mooer Blade is fantastic.
