    More precisely, the Evolution Orange Underdrive: https://www.youtube.com/watch?v=v4xQpLBLS8M#t=90

    Set your amp to crunch, turn on the pedal and it cleans up your sound without any loss of tone. A great idea, I think, since I'm never satisfied with just rolling off the guitar volume. Anybody know of any other pedal that does the same thing?

    Didn't Paul Gilbert use a similar pedal?

    there was just a thread like 2 weeks ago asking if this existed.. almost everyone said no but the HBE Detox was mentioned.

    What would be the difference from rolling down the knob ? I Mean, does it just lower the signal level ?

    Now that you mention it, I've seen a demo of him using that pedal to the same effect. He's also used a compressor to clean up a dirty signal.

    I think it lowers the signal but also applies some eq to optimize your clean tones.

    I assume bjorn designed this?

    I think it's brilliant.

    However, I use 50's wiring in humbucker guitars and treble bleeds in single coils, so it's never muddy when I roll back the volume. But bass and bigness do get lost.
    That said, I like to move my volume pot, not from one place to another, but everything from 10 down to 3. I ride it constantly, kind of like Landau does.
    So not sure abut this one.
    But I might get it anyway. It could provide two ranges to move the volume pot in. Say 7 to 10 with the pedal on and off. There ya go. That's what I'll do.
    Want.
