Okay, okay, yet another question you'd think I'd know the answer to after all these years... I want to use a power supply now and then with a couple of pedals that are -Center, +Ring. Search though I might among my rat's nest of adapters, I can't find any that announce how they're wired.
Any clues on who's adapters are wired that way? Any pros and cons of using certain ones over others? |

Hey Chris--I'm surprised. I have a rat's nest of adaptors and they are all marked. The only ones that do not specify polarity are AC/AC which has no polarity (rather than AC to DC).
You may very well know this but this diagram depicts tip negative:
It is sometimes referred to as "Boss" style. |

Thanks, Jon. I checked my Boss adapters and they have a slightly more cryptic diagram that I now know to feel confident means -center/+ring. Though the diagrams certainly look like they mean that, I am well known for wildly misunderstanding what the rest of the world seems to see as unambiguous markings and directions.
Anyone have brands of power supply you recommend or recommend against these days? |

This is you, Chris, and not some idiot running 10,000 watts of pedals on a stupid pedal board like someone I know, so you don't likely need a heavy duty supply like a Pedal Power 2. I've never had trouble with the One Spot

Center negative is THE standard for 9v guitar pedals with coax connectors, Boss, Ibanez, Fulltone, and the other gazillion pedal makers.
Center positive is rare and will likely be associated with a pedal that came with its own supply, and likely NOT 9v, maybe 12v or other. If a pedal is not marked, you can almost bet it's gonna be the standard 9v center negative type.
Also, it's common that the types that use non-standard supplies will have a coax jack center pin that's oversized and won't even allow you to plug in the standard type.

| You can always check these wall warts and different power supplies with a volt meter to determine polarity. |

Brad, I've found that computer peripherals that run on 9V (fortunately rare) are usually center positive, and some with plugs close enough in size that they'll plug up.
Annoying.

Chris, if you are having trouble determining the polarity of your transformers, you can check them with a voltmeter to determine the polarity. If they're not what you need cut the wire into an reverse the wires. Just be sure that they are the correct milliamps.

The Danelectro DA-1 powers most Boss pedals at about a third the price of a Boss. Caveat: haven't checked these lately for compatibility/availability.
