Big muff pi’s power supply question.

skunkwerx

I’ve become confused tonight. 

I have a green russian big muff pi inbound any day now.  (pmt lost it somewhere between southend and london)

Does anyone have one or know what its power adaptor requirements are? 

Looking at the image on the front of the big muff near its power socket, it has a O with a - inside it, and around that there is another circle with a +. So I presume its centre negative right?
Just couldnt find anything about its barrel connector size.

I’m hoping it will run off a Strymon Zuma power supply, which is centre negative,  5.5mm x 2.1mm. 


Literally every google search just throws up Ehx.com forum threads in which people state it needs a ‘positive tip’ power supply. Which seems wrong. 
Unless the US and Australian big muffs are centre positive...

Older EH pedals with a mini-jack power socket do need a positive-tip plug.

Modern ones with the barrel-type socket need a standard centre-negative plug.
