Best Pedalboard Power Supplies for Clean Guitar Tone

Pedalboard power supplies provide clean, stable power that prevents the noise and hum plaguing daisy-chain setups. Isolated outputs prevent ground loops between pedals while delivering the specific voltages different effects require. Quality power significantly improves overall pedalboard performance.

Best Professional Power Supplies

The Strymon Zuma ($299) delivers premium isolated power with high current capacity. The nine 500mA outputs handle demanding digital pedals easily.

The Voodoo Lab Pedal Power 3 PLUS ($299) provides eight isolated outputs with comprehensive voltage options. The legendary reliability serves touring professionals.

The Cioks DC7 ($259) offers seven outputs with exceptional noise performance. The compact design fits under pedalboards efficiently.

Best Mid-Range Power Supplies

The Truetone CS12 ($189) delivers twelve isolated outputs at accessible pricing. The high current capacity suits mixed analog and digital boards.

The Voodoo Lab Pedal Power 2 PLUS ($199) provides eight isolated outputs with the reliability Voodoo Lab built its reputation on.

The MXR Iso-Brick ($179) offers ten isolated outputs in a compact format. The pedalboard-friendly design includes mounting brackets.

Best Budget Power Supplies

The Truetone 1 Spot Pro CS6 ($129) provides six isolated outputs at entry-level professional pricing. The quality exceeds the price point.

The Donner DP-1 ($39) delivers basic isolated power affordably. The starter option suits small pedalboards with modest requirements.

Why Isolation Matters

Isolated outputs provide separate ground references for each pedal. The isolation prevents ground loop hum that plagues connected pedals.

Non-isolated daisy chains share ground connections between pedals. The shared path creates loops that introduce noise.

High-gain and digital pedals particularly benefit from isolation. The sensitive circuits reveal noise that others mask.

Current and Voltage Requirements

Current capacity must meet pedal demands. Digital pedals often require 200-500mA while analog pedals typically need 20-100mA.

Voltage options beyond standard 9V serve diverse pedals. 12V and 18V outputs power pedals requiring higher voltages.

Sag simulation on some supplies recreates dying battery characteristics. The feature suits vintage-style overdrive and fuzz pedals.

Mounting Considerations

Under-board mounting keeps power supplies hidden. Pedaltrain-style boards provide space for this installation.

On-board mounting occupies pedal space but provides easy access. The visible placement suits troubleshooting.

Mounting brackets included with quality supplies simplify installation.
