I’ve seen a LOT of threads asking the same question, so stikying this would be useful.

If you’re going to change your power supply (ps) then you must look into this:

input voltage: if your country runs on 220, then the ps must have 220v on the input, if it’s 110, 110 and so on
output voltage: it must be exactly what the pedal needs. Not more, not less. More can and maybe will burn the pedal, and less will make it work unproperly (but it IS safe to undervolt/sag a pedal)
output amperage: it must be at least what the pedal needs. More is fine, less isn’t. So, if you have a pedal that runs with 45mA, the ps must supply 45mA or more.
Polarity: If the pedal needs center negative/tip negative/negative ground, etc. then the supply must provide the correct polarity.
Type of conector: must be same size, if not, won’t fit, and cause problems
Type of current: If the pedal needs DC (direct current) the ps must be an AC/DC one. If the pedal needs AC (alternating current) then the ps must say AC/AC.

If you have a power strip or a pp2+ or onespot, all of this applies also.

Extra tip: It’s better if the power supply is regulated and filtered. Because unregulated supplies provide more voltage than it says, and then, when the pedal takes the current, it gives the right voltage, which can make it not work 100% fine.

If you need to power up several pedals (more than 1) then use a 1spot (daisychain) a pp2+ (isolated grounds) and there are many others within a wide range of prices.

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.

Thanks to Julian and Ron

A regulated supply is better because the supply will always give the correct voltage, regardless of the current being drawn.  The exception is if it can’t supply enough current to the pedal, the voltage will drop.

As stated above, a well-regulated and filtered supply will always be your best bet, especially on digital pedals.

I’ll bump this. if somebody is against this, then well, say it. It would answer many threads/questions/doubts, etc.

I see a lot of forumposts with questions about nthis kind of questions, so another bump^^

bump…...........

On one side of the instructions for my Micro Pog it says that it’s fine to use a Boss power supply for the pedal, on the other side of the instructions it says don’t use anything other than the supplied adaptor.

Help please…..

Cheers.

If you use a powersupply with the same voltage and the same mA or more than the pedal needs, you’re just fine, I also use a Boss adaptor for my Microsynth, and it had the same in the manual..

As long as the voltage is the same (within a volt) and the current is the same or higher, you’re OK.

Great.

Many thanks.

bumped (again)

I can’t find any info on the type of connector, I’ve managed to match voltage, polarity, with enough current but I don’t know if the connector will fit?

For a memory man/ polychorus.

If it’s the new version you need that barrel conector. If you have the old version, with a small jack, then it’s 1/8” mono plug

Yeah the new version so that should work? If it doesn’t fit I guess I can always just cut the wire and use the 24V adapter and solder it to the supplied adapters connector(which doesn’t work at 230V unfortunately)

Yeah, then it’s the barrel type

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.
