It's about ¤70 more than the standard Blues Driver, but the Waza is crafted a bit differently. Parts are carefully selected from the highest quality and new features are added to these units to give them a bit more versatility. The standard Blues Driver is a beauty for sure, but the Waza is a work of BOSS art. Is it worth the extra ¤70, I can't say for sure. Each user will have to judge for themselves. Personally, I've very happy with this unit, glad that I've rediscovered the awesome quality and engineering of BOSS. My original 1981 CE2 is still in use and functions like it did the day I received it BOSS is really built to last. BOSS continues to innovate and create some of the best pedals on the market. Forget the boutique craze. The big boys do it well and BOSS is the Boss.
