the Big Muff has some high pass filters in it to reduce crossover distortion and give that creamy sustaining tone on lead parts.
The wicker deactivates it, making things get a bit nasty.
It’s cool for darker tone settings because it allows your high notes to shine through.
That’s the wicker part. The tone switch allows you to bypass the tone circuit altogether. The combination of the two makes the BMP a totally insane pedal. :rawk:
