The MOEN polarity converter allows a standard effect pedal 9v AC adapter adaptor (2.1mm ID, 5.5mm OD plug, negative center) to power pedals requiring a positive center plug.

Useful for odd pedals requiring a positive center plug, eliminating the need for an extra AC adapter.

Specs:

• Converts polarity either way (negative/positive or positive/negative)
• Suitable for use with Daisy Chains
