10 Best Guitar Pedal Power Supply 2025 in the United States

The Donner DP-1 Guitar Power Supply is a practical choice for guitarists looking for a versatile and reliable power source for their pedals. It features 10 isolated outputs, which include seven 9V 100mA outputs, one 9V 500mA output, one 12V 100mA output, and one 18V 100mA output. This variety allows it to cater to a wide range of pedal requirements.

The inclusion of independent short-circuit protection ensures that if one output fails, the others will continue to function, providing added reliability during performances or practice sessions. The noise reduction circuit design is another notable feature, helping to minimize unwanted noise and ensuring a cleaner sound. With an aluminum alloy build, it is both lightweight and durable, making it easy to transport and resilient to damage. The compact size further adds to its portability, fitting comfortably on most pedalboards without taking up too much space.

The blue LED lights are not only functional, indicating power and short circuit status, but also offer a cool aesthetic. On the downside, some users might find the 100mA outputs insufficient for high-power pedals, and the fixed output voltages may limit flexibility for those with more specialized needs. Additionally, while the aluminum build is durable, it may not be as robust as some higher-end models made from more premium materials. Despite these minor drawbacks, the Donner DP-1 is a solid choice for guitarists needing a reliable and versatile power supply for their pedal setup.

The MXR DC Brick Power Supply is a solid choice for musicians looking for a reliable power source for their pedalboards. One of its biggest strengths is the ability to handle twice the power of its predecessor, making it suitable for more power-hungry setups. It comes with eight 9V outputs and two 18V outputs, which is quite useful if you have a variety of pedals.

Additionally, each 9V output has a red LED indicator that lights up in the case of a short, which is a handy feature for troubleshooting. The product is relatively compact with dimensions of 4.3 inches in length, 2.7 inches in width, and 9.2 inches in height, making it portable and easy to fit onto most pedalboards. With a weight of 1.55 pounds, it is also fairly lightweight for its class. The build quality is robust, ensuring durability over time.

However, there are a few downsides to consider. The power supply is not fully isolated, which means there could be some noise issues if you have sensitive pedals. Also, it is manufactured in China, which may be a concern for those who prioritize products made in the USA. This product would be particularly beneficial for guitarists who need a versatile and dependable power supply for a moderate number of pedals, without requiring fully isolated outputs.
