A Guide to Selecting the Best Pedalboard Power Supply
Choosing the right pedalboard power supply is essential for any guitarist or musician who uses multiple effects pedals. A good power supply ensures that your pedals receive clean, reliable power, which helps prevent unwanted noise and performance issues. When shopping for a power supply, it's important to consider the types and number of pedals you use, as well as the specific power requirements of each. Understanding the key specifications will help you make a choice that keeps your setup running smoothly and quietly.
Output Voltage
Output voltage refers to the amount of electrical pressure the power supply delivers to your pedals, most commonly 9V, but sometimes 12V, 18V, or even 24V. This is important because pedals are designed to operate at specific voltages, and using the wrong voltage can cause them to malfunction or even get damaged. When looking at output voltage, check the requirements of each pedal you own. Some power supplies offer multiple voltage options, which is useful if you have a mix of pedals with different needs. If all your pedals use 9V, a simple supply will do, but if you have a few that need higher voltages, look for a supply with selectable outputs.
Current (mA) per Output
Current, measured in milliamps (mA), is the amount of electrical flow each output can provide. Each pedal draws a certain amount of current, and if the supply can't provide enough, the pedal may not work properly. Power supplies list the maximum current available per output, and you should make sure each output can handle the needs of the pedal you plan to connect. For small analog pedals, 100-200mA is usually enough, but digital pedals or multi-effects units may need 300mA or more. Add up the current needs of your pedals and make sure your power supply can handle them comfortably.
Number of Outputs
The number of outputs determines how many pedals you can power at once. This is important because daisy-chaining too many pedals from a single output can cause noise and reliability issues. Power supplies come with a range of outputs, from just a few to a dozen or more. Count the pedals you plan to use and choose a supply with at least that many outputs, ideally with a couple extra for future expansion.
Isolated Outputs
Isolated outputs mean that each output is electrically separated from the others, which helps prevent ground loops and unwanted noise. This is especially important if you use a mix of analog and digital pedals, or pedals from different manufacturers. Non-isolated supplies are cheaper but can introduce hum or buzz into your signal. If you want the quietest, most reliable setup, look for a power supply with fully isolated outputs.
Physical Size and Mounting Options
The size and mounting options of a power supply affect how easily it fits on or under your pedalboard. Some supplies are compact and designed to fit under popular pedalboards, while others are larger and may need to sit on top. Consider the space available on your board and whether you want a tidy, hidden installation or don't mind the supply being visible. Check the dimensions and mounting hardware included to ensure compatibility with your setup.
International Voltage Compatibility
International voltage compatibility means the power supply can work with different wall voltages (like 110V in North America and 220V in Europe). This is important if you travel or tour internationally, as it ensures your supply will work anywhere with just a plug adapter. If you only play locally, this may not matter, but for travelers, it's a key feature to look for.
