I was caught between purchasing an Angry Charlie when I found this pedal, and figured how could I turn down an added Blues Driver? It's exactly what you'd expect, with the cranked Marshall growl of the JHS side, and the buttery overdrive of the Boss side. Parallel mode also offers a killer tone. My only complaint could be the need for the extra footswitch to really get the mot of the pedal, but if you have one already, the tones are endless and accessible. Would highly recommend.
