Pedal Power® 4×4

Audiophile quality analog power for your high-current digital pedals and 9-volt battery classics! 

Pedal Power® 4×4 is a linear (analog) power supply that can properly power up to 4 digital power-hungry effects like those from Strymon, Eventide, Line 6, TC Electronic and more, plus 4 standard 9-volt battery stompboxes. Perfect for large pedalboards, Pedal Power 4×4 features 8 completely isolated, filtered, and regulated output sections that will keep your pedals dead quiet and free from high-frequency noise that occurs with digital “switching” power supplies.

Pedal Power 4×4 features an internal thermometer that controls a silent fan keeping the unit cool even under the most adverse heat conditions of outdoor festival stages. Even with poor AC line conditions, it delivers clean, consistent power. Handmade in the USA using the finest components, Pedal Power 4×4 was designed to meet and exceed the needs of our most demanding professional users.



Ground loops cause hum and the solution is to break the unwanted ground path. Isolation is the best way to do it. Unlike many power supplies, Pedal Power isolates every output. This eliminates tone-robbing interaction between other effects. Pedal Power runs everything from vintage overdrives to modern digital marvels in a way other power supplies simply can’t.

Proprietary Balanced Transformer
Typical transformers, like those used in a wall wart, create large magnetic fields that cause hum in any audio path near it. Pedal Power uses custom-designed, ultra-low noise toroidal transformers with separate balanced windings for every output allowing even the most sensitive pedals to be dead quiet.

Linear Power
What’s good for charging a cell phone is NOT good for your pedals. While digital switching power supplies are small and inexpensive, they also generate noise. Pedal Power uses an audiophile quality linear supply for consistently stable, clean, pure power.
