I have the following foot pedals:

... and of course would like to add more. :)

I'd like a single power supply to rule power them all (for example this Chord 9Vdc Power Bank).

I'm not necessarily after a recommendation per-sé, as it'll go out of date eventually. However, what should I be checking/looking for when trying to choose one of these adapters so I get one that will work without frying my gear.

I'm thinking adding up amps and checking centre-pin polarity etc, but I don't know for sure.

I'm powering 10 pedals with a single 1spot power supply. You just have to make sure that you pedal do not consume in total more that power supply output (those mA).

T-rex makes some nice power supplies.

  • Cool. Are the pedals all the same or do they have different brands and power requirements? Are they all centre-pin positive? Oct 11, 2011 at 11:58
  • They are center pin negative and they're all different. Korg Pitchblack, CAE MC-404, VoodooLab Microvibe, Fulltone Catalyst, Xotic AC+, Ibanez BC-9, EHX Stereo Pulsar, TC Electronic NovaRepeater.

There are a wide range of companies that produce power supplies suitable for multiple effects. Core factors which should help your decision:

  • What is the total current output? This must be higher than the total current needs of your pedals
  • What is the individual current available? This must be higher than an individual pedal's needs
  • Can it cope with centre positive, centre negative or odd connector types?
  • How robust is it?
  • How heavy is it?
