Here’s a compilation of adapters/power supplies meant for use with guitar pedals. I have not listed pedal-specific power supplies (such as the one that comes with the Whammy, for instance), as they are meant for specific pedals only. I have also not taken my own preferences into account – this is more an effort to present all the options 🙂
Also, in our globalized world, it is becoming increasingly common for manufacturers to sell the same product under various different brand names. When a particular supply starts to crowd the list with too many rebranded copies/spinoffs, I will leave the one I perceive to be the ”original” unit in the main list, and throw its siblings in a separate list at the end. Hopefully, this will make the main list easier to navigate, as well as making it easier to spot the similarities.

The golden rules of using power supplies:
Get a proper adapter. If it isn’t specifially made for audio applications (i.e. if it’s a generic ”will replace all adapters” type), it’s not made for audio applications, and shouldn’t be used. Yes, the same rules still apply – get the plug polarity, voltage and current (mA) capacity right, and it will work – but it probably isn’t well enough filtered. Your rig will show its dislike by humming loudly…
Get to know your pedals – before you plug in any adapter. Find out what kind of power they want (AC or DC), how much of that power they want (current draw in mA), and how it wants it delivered (plug/jack polarity). If the pedal says ”9vAC” or ”9v ~”, you can’t use the same adapter as to your Boss pedals. AC means ”alternating current”, which alters direction 50-60 times per second. DC means ”direct current”, which flows evenly from positive to negative. Also, if you plan on buying a switching type adapter, make sure it will not clash with your delay/reverb etc pedals (digital pedals and clock-based analog ones) – if you hear a faint whining sound, the switching adapter will not work for you, and the only recourse is to get a transformer based adapter.
Forget the terms ”negative tip” and ”positive tip” – those terms apply to the 1/8″ mini tele plug that to my knowledge now only is used on the ProCo RAT, the Ibanez reissue TS-808 and the old-style DOD pedals (all of which want a positive tip, btw). You might also find one or two Electro-Harmonix pedal in this group (beware, though – not all of the E-H pedals use 9 volts DC). All other ”normal” pedals use a 2.1mm barrel type plug, with the positive carried on the outside of the plug. The center pin in the adapter jack is therefore negative, and the term is ”center negative”. But plug polarity is one thing – ground polarity is another thing you need to know about. Again, most pedals (all ”normal” effects such as Boss, Ibanez etc) are the same – they have negative ground (battery ”-” goes to ground). But some effects – mainly ”boutique-type” germanium fuzz pedals – have positive ground instead. On those pedals, the adapter jack polarity is normally also reversed, but they don’t have to be – it doesn’t have anything to do with the fact that they are positive ground. The main thing to remember is that you can’t feed these pedals power from the same source (daisy chain or non-isolated psu) as you use for the others – that will short the entire power supply out, and make your pedals go quiet (at best – at worst, your gear will be damaged). For those pedals, you have to either use batteries, get a separate adapter (check the plug polarity), or get a psu with isolated outputs. Check the list above – there are only a handful of power supplies with isolated outputs.
You can never have too much power. You can kill your pedals with too much voltage, but not by the adapter having too much current. The pedals will only draw as much current as they need, regardless of the amount available from the adapter. But the bigger the adapter, the less strain you’re putting on it. A rig that draws 185 mA in total really needs a bigger adapter than 200mA – you don’t keep your car in first gear, at 5000 rpm, just because the redline is at 6000, do you? So, basically, unless there are other limitations – such as finances, for instance, or that you’re using the ”power thru” jack on a Boss TU-2/LS-2/NS-2/PSM-5 (which aren’t guaranteed for more than 200mA) – get quite a bit more than you technically need.
