Morley Hum Exterminator

The Morley Hum Exterminator is an innovative device that filters out unwanted voltage in the ground line to eliminate irritating ground-loop hum. Simply place the Hum Exterminator on the end of the power cord of gear experiencing ground-loop issues, plug it into the wall outlet and that incessant buzzing is gone—with no signal loss or tone sucking.

Eliminate Ground Loop Hum Without Lifting the Ground

Unlike devices that remove the ground connection altogether, the Morley Hum Exterminator provides a solid, safe ground while filtering out the unwanted voltage and current causing the hum. This means no loss of shielding or shock hazard—just pure, clean power and signal. For guitarists and other musicians, this translates to freedom from distracting noise without sacrificing tone.

A Simple, Foolproof Solution

The Morley Hum Exterminator couldn’t be easier to use. Simply plug it in, and the hum disappears. No manual ground lifts, no rewiring, no hassle. It’s a plug-and-play solution you can set up in seconds. Completely passive and maintenance-free, the Hum Exterminator draws no power on its own, so it won’t drain your gear’s batteries or add noise. It’s rated for any device drawing 6 A or less, making it suitable for powering a wide range of musical equipment.
