What you need to know
- Power up to 7 effect pedals in series from a BOSS NS-2, LS-2, or TU-2 pedal, or from any 9V source equipped with a female connector.
- 8 male 9V plugs wired in parallel to distribute the same voltage to multiple pedals quickly and easily.
- Insulating caps included to protect unused plugs and keep your pedalboard clean and safe.
- Pay attention to available amperage: the power supply must provide at least the sum of the current consumption of all pedals used.

An Essential Pedalboard Accessory to Multiply a 9V Output
When building a pedalboard, you quickly end up with several pedals to power, sometimes without wanting to add a second power supply. This "daisy chain" type extension cable meets exactly that need: it allows you to distribute a 9V output to multiple pedals while maintaining a simple and quick setup. It is especially practical if you use a BOSS pedal with a dedicated power output (NS-2, LS-2, or TU-2), or any other 9V source with a female connector.
Who It's For and What It's For: A Simple and Effective Multi-Pedal Power Solution
This cable is designed for guitarists and bassists who want to power multiple effect pedals from a single power point without complex configuration. Ideal for compact pedalboards, rehearsals, backup setups, or minimalist configurations where you want to limit the number of power bricks and cables. It's also a practical solution if you want to chain a selection of low-consumption analog pedals.
Key Features: Parallel 9V Distribution and Connector Protection
8 Male 9V Plugs Wired in Parallel
The 8 male 9V plugs are wired in parallel: each pedal receives the same 9V voltage. Practically, you can power up to 7 pedals in series (with one plug remaining depending on the configuration) from a compatible pedal (BOSS NS-2, LS-2, TU-2) or a 9V source with a female connector. This is a direct and fast approach to distribute power on a pedalboard without multiplying outputs.
Insulating Caps Provided for Unused Plugs
The supplied insulating caps protect connectors you are not using. The result: fewer risks of accidental contacts, better durability of the plugs, and cleaner wiring when not all outputs are needed in your current setup.
Check Before Plugging In: Available Amperage
This cable does not replace a more powerful power supply: it distributes the available power. Make sure the amperage of the 9V source you use is equal to or greater than the sum of the amperages required by all pedals you want to power simultaneously. This check is essential to avoid instability, power loss, or interruptions on your pedalboard.

Plugs a bit too big for the sockets on the sides of the pedals, one or two elbows in the garland would have been better. Otherwise RAS, it is a standard non-insulated cable...

Questions frequently asked
Can the Boss PCS-20A power 7 pedals?
Its 8 male 9 V jacks wired in parallel allow powering up to 7 pedals from a 9 V female jack source, depending on the chosen configuration.
Is the cable compatible with a BOSS NS-2, LS-2 or TU-2?
A BOSS NS-2, LS-2 or TU-2 pedal equipped with a dedicated power output can serve as the source for this cable. The connection requires a 9 V female jack output. Each connected pedal receives the same 9 V voltage.
What power supply is needed for multiple pedals?
The available current at the source must be equal to or greater than the sum of the consumptions of all pedals connected simultaneously. The cable distributes the available power without increasing its capacity.
Can the unused plugs of the cable be protected?
Insulating caps are provided to cover unused 9 V connectors and limit accidental contact.
Are the outputs of the PCS-20A isolated?
The 8 9 V jacks are connected in parallel: they share the same power supply and do not constitute separate outputs. This configuration is suitable notably for a selection of low-consumption analog pedals.
