    Few a few seconds I’m Kurt. Just marvellous.

  • Dave Archer


    Robust build and great sound

  • Adrian Sharman


    I have spent years trying to find a distortion pedal that sounds good with a Strat. This sounds great with a Strat. It does have a distinctive voice which means you need to be sure this is the sound you want. I like the sounds Ronnie Montrose, Jack White and David Gilmour have made and the big muff was a part of that. It is physically huge compared to e.g. a Boss stomp box, but that isn't a problem for me. If size is the only thing putting you off I think there is a mini version.

    Sounds great. There is a reason these are so widely used. Would never use anything else now.

  • Steve Clark


    Good product with a great sound.
