Just a quick one: I'm just asking if someone could confirm the polarity of the Ehx big muff tone wicker. I'm quite confused because it says on the ehx site that "the power jack is centre negative", which from what I can gather is symbolized like this: http://duhvoodooman.com/miscimages/musical/plug_types.gif It is to my understanding that this is the same polarity as that of boss pedals (and all of the other pedals on my board). Therefore I would be able to use the same power supply for all of my pedals? What's leaving me stumped is the logo on the top of the big muff: http://www.ehx.com/assets/jpg640h/big-muff-pi-with-tone-wicker.jpg As you can see the + and the - are the other way around. So is it positive polarity? Thanks for any help in clearing this up for me!
