Double Volt from 3.5mm mini plug source to 2.1mm right angle barrel plug.
This double volt cable uses two 3.5mm outputs from the power supply (such as a Furman SPB-8C and the SKB StageFive PS-55) and adds their voltage together. This cable features two right angle 3.5mm mini plugs for the power supply that double the voltage to a right angle 5.5mm x 2.1mm barrel plug for the pedal. It is typically used with two 9 volt outputs to yield 18 volts, center negative, at the pedal. The voltage from the two outputs is simply added together.
When used with Furman SPB-8C, the center of 2.1mm barrel plug will be negative.
Important: When used with SKB Stagefive PS-55, it’s a little more complicated. The standard polarity setting on the PS-55 will result in a center positive for your effect which is normally considered reversed polarity. Reversing the polarity setting on the PS-55 will result in a center negative which is typically considered standard polarity for your effect. This may seem backwards but that is because SKB (and some old Gator power supplies) used cables that were wired opposite of normal standards adopted by Voodoo Lab, Dunlop, Furman and even SKB’s own PS-45. Weird but true. To avoid confusion, you may want to check your voltage prior to connecting to your effect to be sure the polarity is set correctly.

Pictures: The pictures here show the plug configurations for each cable. Their appearance may differ from the actual cable you receive however they will function all the same. The appearance and price also vary depending on the different options selected. This is due to whether a cable is mass produced or custom made and varies by the available component parts used and the complexity of the custom cable assembly.
Color Coding: Many cables have color coding to differentiate the various configurations however cables in each group may be color coded in slightly different ways.
Length: Choose the length that meets your needs. The approximate length is the wire measured between the plug handles. Overall length is about 2″ greater.
This diagram is for reference only but it gives you an idea of how these cables are measured.
