What pedals is the Electro-Harmonix US7.5AC-400 power supply compatible with?

This Electro-Harmonix power supply is exclusively designed for the EHX Hum Debugger pedal. It delivers a specific 7.5V AC output, which is crucial for the Hum Debugger's unique circuitry. Using this AC supply with other pedals that require DC power or different voltage/current specifications can cause severe damage to your gear.

Why does the Hum Debugger require an AC power supply instead of a standard DC one?

The Electro-Harmonix Hum Debugger requires 7.5V AC power due to its specialized internal design. Unlike most guitar pedals that operate on DC power, the Hum Debugger's unique hum-canceling circuitry relies on alternating current to function effectively and deliver its intended noise reduction performance.

Can I use the US7.5AC-400 Hum Debugger power supply in countries outside of North America?

The US7.5AC-400 power supply is engineered for 120V AC input, making it suitable for use in North America. For international use in regions with different voltage standards (e.g., 220-240V AC), a proper step-down transformer is required to prevent damage to both the power supply and your Hum Debugger pedal.

What happens if I use a standard DC power supply with my Electro-Harmonix Hum Debugger?

Using a standard DC power supply with your Electro-Harmonix Hum Debugger will prevent it from working and could potentially damage the pedal. The Hum Debugger specifically requires 7.5V AC power, and a DC supply will not provide the necessary current type or voltage for its unique hum-canceling circuitry.
