Voltage Doubler 2.1mm DC Cable for 9V or 12V guitar Effects pedals Pedal Board.

Professional Voltage Doubler DC Cable for Guitar Effects Pedals

This custom-built voltage doubler DC cable is designed for combining two compatible isolated DC outputs into a higher voltage supply for effects pedals requiring increased operating voltage.

Built using FOX Two Mini miniature 2 core cable with genuine Switchcraft DCP-762 True 2.1mm DC plug connectors, this cable is ideal for compact pedalboard power routing and professional stage or studio setups.

Important Compatibility Information

This is a voltage doubler cable and must only be used with compatible isolated DC power supply outputs.

• 2 x isolated 9V outputs → 18V output
• 2 x isolated 12V outputs → 24V output

Important: Never use this cable with non-isolated outputs or standard daisy chain connections.

Always verify pedal voltage requirements before use. Incorrect voltage can permanently damage connected equipment.

This cable is wired for standard centre negative guitar effects pedal applications.

Best For

• 18V and 24V effects pedal power applications
• Combining isolated PSU outputs
• Compact pedalboard power routing
• Professional pedalboard systems
• Studio and live pedal setups
