I’d add stuff about daisy chaining:
Positive ground: Some pedals, such as the Nano Clone and Nano Muff OD have positive ground, instead of negative ground. They are normal polarity though. When daisy chained with pedals that are negative ground, they will not work properly. Pedals with positive ground must be on a separate power supply, or on a separate output of a power supply that has isolated outs.
Digital and analog pedals usually don’t daisy-chain well together. Digital pedals should either have their own power supply, or their own output on a power supply that has isolated outs.

May 22, 2010 at 3:59 pm #107820risingorionMemberHello people
I have
I just bought a EHX Cathedral here in Europe (outlet 220).On the box it is written 230 v
on the pedal there is no indication of voltage
on the power adaptor supplied, it is 230vso the question is
If I go to a place where the outlet/voltage is 110/120
Can I just simply change the power adaptor (to a 110v to 9v power supply)?
If it is not enough, what would be the best option:
a)to get a new outlet
b)to modify the pedal
c) to buy a convertor?Thanks!!
May 22, 2010 at 4:10 pm #107798Mr.GrimMemberyes you can just get a new adapter for that area, EHX makes there pedals the same to work in any location, the only difference is going to be the power supply. you just need to buy the one that will convert your areas voltage (110v/220v…ect) to the pedals input (9v,12v,18v,24v)
May 22, 2010 at 4:26 pm #107759SanquiFlerbMemberCathedral will take 9v, doesn’t matter if the outlet is 110, 220 or a 1 000 000 volts, you just need an adaptor that can manage to take that input, and delivers 9vdc, with a correct polarity, sufficient amperage, etc.
May 22, 2010 at 5:55 pm #106723risingorionMemberThanks a lot!!!
The pedal is great!

June 17, 2010 at 4:21 am #109538Stringmusic24MemberI am completely new to the effects world, but I’m starting to put together my first pedal board. The pedals I plan on incorporating are:
EHX Holy Grail (nano)
ENX Deluxe Memory Man
Ibanez TS9 Overdrive
Boss TU2 Tuner
EHX Big Muff
Ernie Ball Volume
DI Box (for an acoustic)What kind of power supply should I be looking for? Could I power all of those off of a PP2+ or not? Some other type of isolated power supply? I’m clueless…….thanks for any help.
July 16, 2010 at 3:55 pm #110285SanquiFlerbMembersorry for late response. you can daysichain 9vdc +(o- pedals and use the 2 12v outs with a special cable to power up the dmm, so the pp2+ it’s good for you.

Question: I’m tossing around the idea the idea of getting either a Muff OD or the Double Muff (leaning towards the latter). Do you know if the Double Muff has positive or negative ground? If it does have negative ground I’ll probably go with the DM as it’ll be one less power issue to worry about and it sounds a little more like an overdrive. And, while I’m at it, does anyone know if the DM even works well with a power supply? I’ve run into an anti-adapter trend with other EH stuff…

Double Muff is negative ground. Should work fine with a quality power supply.

I’m compiling the info along with the proper AC adapters in this spreadsheet:
August 2, 2011 at 3:04 am #101697timiselerMemberThis is a power supply connector question – I’m trying to source a part number for a replacement power connector on a Bass Big Muff. The pedal works fine with a battery, but this connector was mashed on and broke. It is center/tip negative. Nothing special about it, I just want to make sure I order the correct part.
Thanks.
August 31, 2011 at 12:57 am #115642LitebritebandMemberIs the old electric mistress ground negative?
March 27, 2014 at 6:32 pm #119805drusianMemberMine is this model here:
The correct voltage and amperage would be this one?
Stereo Polychorus US24DC-100 UK24DC-100 EU24DC-100 24vdc, 100mAPlease click the right mouse button on the image and ask to display the image. In the forum, there appeared the image of the pedal that is right next to the box.
Do not want to risk burning my pedal.
