This great connector from Truetone will allow you to transform the power from an 18v power supply to a 9v, for use with certain pedals and other devices.

For use with 1 SPOT and other power supplies. 

Powers a 9V effect pedal from an 18V power supply or power brick.

WARNING: Use the Voltage Doubler cable only from 18Vdc outputs. 18Vdc is converted to 9Vdc. Do not use with input voltage greater than 18Vdc. 

WARNING: Check with the pedal manufacturer before using the 18 TO 9 cable. Truetone is not liable for improper use of this cable that causes damage to your pedal.

    Worked a treat! Does what it says on the tin.(packed)

  • Christian Armstrong


    Excellent, does the job exactly as advertised and allows you to use the 18v input for 9v pedals.

  • AJB


    Works spot on! Nice to have an extra two ports to use on my CS12. Back when I needed some they didn’t sell them in the UK so this is a pleasant surprise
