The wicker is great when you roll back the tone, but it tends to make the pedal noisier

Wicker is just a high frequency boost.

I love wicker on and tone off.

Not sure if I will actually like the "tone wicker", in fact I leave both off, but maybe someday I will find a good use for the tone and wicker switches

Gotta love the "Tone Wicker", really gives the Big Muff a unique sound

Leaving the tone on and the wicker off leaves you with the original big puff pi pedal, so no worries if the wicker isn't really your thing
