First of al it's not actually a overdrive pedal, it's heavy distortion with tons of gain. If someone is looking for booster or light overdrive will be dissapointed. It behaves like high gain amp, very natural sounding pedal. Perfect for any heavy styles of music.
One the other hand, it"s very versatile, thanks to internal gain pots for reducing or adding amount of gain for each channel. Not cheap pedal, but worth it's price.
