If your effects pedal needs 18V or 24V of power, Strymon's Voltage Doubler Cable provides both. Simply connect the 10 cm long cable to the 9V or 12V outputs on a multi-power adapter like the Zuma or Ojai and you're all set. The cable can be used to power certain pedals by names like Fulltone, Keeley, MXR and Dunlop.
