Most pedals are centre negative. Check the symbol next to the power jack or in the manual. Polarity only changes the pedal end.

Wrong length? Send it back within 30 days and we'll remake it with your plugs. You just cover shipping and any new parts.
Is this for you?
Yes if you want DC cables cut to fit your board, or you need a plug or setup your supply didn't come with: RCA for Cioks, 2.5mm for HX Stomp, a daisy chain, or a doubler.
Not sure what your pedal needs? Check its voltage, current (mA), polarity and barrel size first. The guide below walks you through it, or email info@goodwoodaudio.com and we'll help.
New to DC cables? Start here.
Every cable has a power supply side (left in the picture) and a pedal side (right), marked on the drawing. Pick the cable type, then the plug for each side, then the polarity and the lengths. The pedal end is a moulded right angle plug on most cables, and the supply end is hand soldered.
Which plug do I need?
Most supplies (Strymon, Voodoo Lab, Truetone and similar) use 2.1mm DC jacks. Cioks supplies use RCA on the supply side. The 2.5mm plug fits pedals with a larger centre pin, like the Line 6 HX Stomp and Eventide H90. EIAJ is for linking modular supplies together, like Cioks DC7 to CE8 or Strymon Zuma to Ojai.
Check your pedal before you order
- Voltage. This one is critical. Too much voltage can kill a pedal. 9V is most common, but never assume. Check the manual.
- Current (mA). A pedal only draws what it needs, so using a 500mA outlet for a pedal that only needs 100mA is fine. Too small and it won't power up properly. Digital pedals often need 300mA or more.
- Polarity. Most pedals are centre negative. If yours is centre positive, choose it in step 3 and the drawing will mark it in red.
- Barrel size. 2.1mm is most common. 2.5mm pins are larger, and are often used on centre positive pedals, but not always. The HX Stomp is 2.5mm centre negative.
Current doubler or voltage doubler?
Current doubler (tripler, quadrupler). Combines 2, 3 or 4 outlets set to the same voltage so their current adds up. Two 500mA outlets give 1,000mA (1A) to one pedal. Great for an HX Stomp or Quad Cortex running off your board's supply instead of a wall wart.
Voltage doubler. Adds two isolated outlets together to give one higher voltage outlet. Two 9V outlets give 18V. A 9V and a 12V give 21V. Check your pedal's maximum voltage before you plug it in. The current you can draw is limited to the weaker of the two outlets. Both outlets must be isolated from each other.
DC Cable FAQ
Which plug do I need for a Cioks supply?
RCA on the power supply side. Pick the plug your pedal needs on the other end.
Can I power several pedals from one outlet?
Yes, with a daisy chain, as long as the outlet has enough current for all of them combined and they all need the same voltage and polarity. Low current pedals like overdrives and buffers are perfect for this. Make sure your pedals are safe to share power. Typically, basic pedals without modulation or digital effects are safe to share, like overdrives, compressors, active volume pedals and buffers, but check with the manufacturer to be sure.
What does centre negative mean?
It describes which part of the plug carries the positive voltage. Most pedals are centre negative. Look for the polarity symbol near the power jack. If it shows the minus sign on the centre dot, it is centre negative, and the outer metal sleeve of the DC jack carries the positive voltage. If it is centre positive, the centre pin carries the positive voltage.
What cable do I need for an HX Stomp?
A current doubler with a 2.5mm right angle plug, centre negative. Tap "HX Stomp cable" at the top of the page and it sets everything for you. All you need to do is choose the length.
Why is the doubler jumper fixed at 4 inches?
On a voltage doubler the two supply plugs are joined by a short jumper. 4" suits two outlets next to each other, which is how almost everyone uses one. If your outlets are further apart, email info@goodwoodaudio.com before ordering.
Is a 24V EIAJ cable safe for my pedals?
EIAJ cables link modular supplies together, for example a Strymon Zuma to an Ojai. EIAJ outputs are 24V, so never plug one into a pedal unless you are certain it takes 24V. EIAJ outlets are often not isolated, so listen for extra noise through your amp before committing.
What if I get a length wrong?
Every cable is built to your spec, so we can't resell it. If a length is off, send it back within 30 days and we'll remake it with your existing plugs, with no labour charge. You just cover shipping and any new parts it needs. Email info@goodwoodaudio.com first so we know it's coming.
Are you responsible if the wrong cable damages my pedal?
We guarantee your cable will be exactly what you ordered and clearly labelled, or we'll replace it or refund you. We can't take responsibility for damage caused by using the wrong voltage, polarity or cable, so check your pedal's manual or ask us first.
