power supply for my effect pedal

Why is the fairly cheap, low current power supply so expensive from Amazon?
I have found other products sold by Amazon costing much more than in local stores. They are Gouging!

The things that are critical are the voltage, and whether the centre of the connector is positive or negative.
It's fine if the PSU has a somewhat higher current rating; the device will only take the current it needs, regardless.

Both the item in your photo and the amazon PSU are 9V with positive centre connection, so it should be fine.


You do have to be really careful with guitar pedals and their power supplies, as traditionally they use connectors with negative inner (and positive outer).
Swapping one of those with another device that uses the near-universal positive centre wiring can cause serious problems or damage...

anyway, this is the pic from the back of the pedal, and here is the link for power supply. this should work, right? also there are some 9V adapters but 1000A.
what will happen if i connect it to the pedal?
