10 Best Guitar Pedal Power Supply 2025 in the United States

The Voodoo Lab Pedal Power MONDO is a robust power supply designed specifically for guitar pedal setups, offering 12 fully isolated outputs to prevent annoying hum and ground loop noise. This isolation is a big plus if you use multiple pedals and want clean, interference-free sound. It supports all standard 9V pedals and includes six outputs that supply extra current, which is great for modern digital pedals that need more power. Two outputs even simulate a 'sag' effect, mimicking a low battery feel, which can be useful for certain vintage-style effects.

It delivers a solid 240 watts of power, but it is fairly large and weighs around 4.3 pounds, making it less portable than smaller options and better suited for a stable pedalboard setup rather than frequent travel. The build quality is reliable, and many users praise its durability. One limitation is that it only works on 120 volts, so if you’re outside the US or Canada, you’ll need a voltage converter.

If you have a complex pedal rig with a mix of analog and digital effects, this power supply serves well by delivering clean power with plenty of outputs. For those with only a few pedals or a need for something very compact, it might be more than necessary.

The Voodoo Lab PedalPower 3 is a solid choice for guitarists needing reliable power for multiple pedals. It offers 8 isolated outputs, each delivering 500mA, which means it can power a variety of pedals, including those that need higher current. Six of the outputs provide standard 9V, while two can switch between 9V and 12V, adding flexibility for different pedal requirements. Isolation is a big plus here, as it reduces noise and interference, helping your pedals sound clean and perform at their best.

The unit is compact and lightweight (just under 2 pounds), making it easy to fit on pedalboards without adding much bulk. Its aluminum build feels sturdy and durable, suitable for both home use and touring. Another handy feature is the X-LINK ports, allowing you to connect additional Voodoo Lab power supplies to increase the number of isolated outputs if needed. The power supply also supports international voltage, which is great for touring musicians.

One minor downside is that while it's very reliable and well-built, it has a higher price point compared to some simpler power supplies. Additionally, it mostly suits those with moderate to large pedal setups due to its number of outputs and current capacity. If you have just a couple of pedals or low power needs, this might be more than necessary. But for most players looking for clean, noise-free power with flexibility, the PedalPower 3 is a dependable and well-regarded option.

The Strymon Zuma is a high-quality power supply designed for guitar pedalboards, offering strong reliability and quiet operation. It provides nine isolated outputs, each delivering 500mA at 9V, with two outputs that can be switched between 9V, 12V, and 18V, making it very versatile for different types of pedals. The dual isolation system helps eliminate noise and ground loops, ensuring your effects sound clean and true.

Its ability to expand with additional units via a 24V expansion bus means it can grow with your pedal setup, which is great if you have many pedals. The unit is moderately sized and weighs about 2.5 pounds, so it’s portable enough for gigging musicians but not ultra-compact. Build quality is solid, reflecting its professional-grade design, and it supports international power standards for worldwide use.

The main downside is that this power supply might be more than what casual or beginner players need, both in terms of cost and capacity, since it’s designed to handle complex pedalboards demanding high current. For serious guitarists looking for a dependable, noise-free power source with flexibility, the Strymon Zuma represents a strong choice.
