On sale this Digitech's answear for Boss BD-2 Blues Driver , which is darker , more dynamic and more transparent effect than f.e. SD-1 , Bad Monkey and other tubescreamer-type effects. This one though instead of having just one "tone" knob has two pots which can shape the eq of sound . It also features the cab simulation from which it can be led straight to the mixer . I can also recommend other effects from this series like : Bad Monkey (like TS-9) , Hot Head (like DS-1), Digidelay (like DD-6) , Dynaverb , Death Metal.. Synth Wah.. (like nothing else)

Anyway , mine works without problems . Small scratches on sides. I'm selling only the device , with original box .
