Question:
The number of pedals that I have has increased lately, so I bought a daisy chain to power them all so I wouldn't have to use wall warts or batteries for each.
Problem is, several of my pedals are Danelectro, and on the bottom it says the milliamps that the pedal requires, and it also says "center negative." I assume that means that the charge going to the pedal must be negative? However, my other pedals, like my Boss DS-1, are not center negative.
I have a wall wart that supplies more than enough mA to provide power to several pedals at once if hooked to a daisy chain, but when I hook it to the daisy chain it will not power anything if hooked into a Dan'O, and will only power the first pedal if hooked to anything else (DS-1). The daisy chain also says "center positive" on the package.
Does this mean my daisy chain is no good for my Dan'O pedals? If so, are there "center negative" daisy chains? ( I would assume there are, but never hurts to ask.) I guess what I'm asking is, is there any way to power all my pedals with my current daisy chain without buying more stuff (seeing as I'm a cheapo and all.)
Thanks in advance!

As far as I know, Boss pedals are center neg/ground and the barrel is the +. My Dan'o fish and Chips and the DaddyO I had are the same as the Boss, in fact I use the same power supply and connectors that I used for the Boss's when I had them, including a DS-1. My Digitech Bad Monkey is also the same. I have kinda assumed that Boss or some other company pretty much set a standard years ago that others follow. I don't know if there are 2 versions of your unit or not, but I believe that you need the center conductor to be neg/ground for Boss and DanO. If you can't exchange the unit, all you would have to do is cut and splice the ends back on with the wires reversed.
The one pedal that lights up - does that one perhaps have a battery in it...?
Answer:
I think most pedals are compatible. I have Dano's, a Boss BD2 and a Korg DT-10 tuner than can be connected to my board (in effect the same as a daisy chain) and are powered a One Spot that will be able to power up to a total of 1800 mA I believe. The only thing that is not compatible is my Tonebone because it's a 15 v pedal. Also, some pedals (don't know which ones though) require RCA type connectors. The Dano's and Boss's have the same center negative connectors.
Answer:
Well, they may both have negative connectors, but the daisy chain's center is positive. I cut the wire and switched the wires inside and then plugged it in...nothing.
Anyone know where to buy a negative-center daisy chain?
Answer:
where'd you get the daisy chain at? I have four daisy chains and they're all center-negative. The Danelectro, Roland, Godlyke and Visual Sound chains are all center negative and one of these should be available at your local guitar store.
Answer:
dumb question, but would a daisy chain going out of a boss know which side was positive? Wouldn't it retain the charachteristics of the power out it was attached to?

I think so. It works on my noise reducer nomatter which way I plug it in.
and to byrnnyrb, it might juist be something wrong with the daisy chain or something because I have had four or five dano's and everyone of them worked with my daisy chain (the 1spot)
Answer:
Well I got a 1 Spot daisy chain (not the powersupply and everything, just the daisy chain.) It works as far as powering all the pedals, but there is a fairly loud hum, which is present even when none of the pedals are on. It's not noise that's normally induced from distortion pedals, as I have the noise gate on my RP200, and even with it all the way up, the hum is still there. My thought is that it is RF interference or something like that, as the hum seems to get louder if I put another power supply close to the daisy chain.
Ideas?
Answer:
what kind of power supply are you using? how much power does it supply? is it possible that you're overdrawing your supply?

It's just a walmart wall wart, but 1700mA, so that's plenty for several pedals at once. But could it also be causing the hum that I'm hearing (which is still there after a noise gate/silencer), because of low quality or something? The daisy chain's fine, and everything's getting power, but that hum is pretty annoying.

what all do you have on your chain? while it is possible that your supply is noisy (while some non-guitar supplies work well, others are generally used in situations where line noise isn't converted to sound and thus can be quite noisy)...it's also possible that something in your chain has a poor power buffer and is casuing the noise. it would require its own supply. this problem existed with early Line6 ToneCore pedals.

Yup. Wires conduct according to the applied voltage. Building pedals (or anything!) would be a nightmare if wires were polar devices .
byrnnryb, Walmart wall warts (despite how much fun it is to say aloud) are terrible for powering effects. You're not over drawing it. 1700mA could easily power 20 pedals. Even if it's things like delays that suck a lot of juice. The problem is probably a lack of filtering in the adapter.
Now the less current you draw (i.e. the fewer pedals you power) the less noise you'll have. That doesn't mean you're exceeding the current rating. That just means the rated current for the adapter doesn't necessarily tell you anything about the voltage ripple (noise) for a given current draw. 1700 mA means that's how much current you can draw without damaging the thing. But you might find that 200mA is the limit to keep the noise down to a reasonable level.
