The Joyo JF-02 Ultimate Drive, as the name suggests, is a one versatile gain pedal effect. Depends on the setting of the channel switch, all the way until approx. 10 O'Clock it delivers a relatively clean overdrive, between 10-12 O'Clock the healthy overdrive comes to play and north of that it is a distortion territory. We found it to be a nice overall pedal, while it is not the perfect overdrive or distortion, it is a pretty good general gain pedal for those who need "one that does it all". The JF-02 Ultimate Drive is actually Joyo's best selling pedal as far as we know.
