The SPF-1 Power Filter is designed to connect between your pedals and the DC power supply. It filters out any noise from the power supply adaptor very effectively.
Noisy power supplies are more common now as most use switch mode technology to reduce size and weight, but can have high frequency noise on the output.
If your pedals are noisier when using an adaptor, compared to batteries, the SPF-1 is for you!
