Notes
The main cool thing of this pedal in my opinion is the sparkle knob, that adds upper harmonics for a brighter sound, that I very liked.Another useful feature is the 21dB clean boost that can be used independently from the overdrive effect to push your amp. The booster is located after the overdrive circuit so when used with the built in overdrive effect and a clean amp, it won't create heavier gain, rather punchier and louder sound.
Example Settings
