If you use a pedal that requires a Mini Jack d.c. inout then this is the answer. Just pop it on the end of one of the DItributor cables if you’re usinga TS-808, or on the end of one of our adapters if you need it for something a bit special. If you are using an old 18V Electirc Mistress for example, just put it on the end of one of our Doubler 9-18V adapters and plug straigh into the Mistress.
