The Hum Debugger from Electro-Harmonix is a hum eliminator designed to clean up your signal chain so that hum will not overtake your guitar sound. The Hum Debugger connects to your guitar, like any other effects pedal. It is enclosed in a tough and compact die-cast chassis, and comes with a 7.5 VAC 400 mA power supply.

The Normal/Strong toggle switch sets the level of hum elimination. In

Normal mode, the Hum Debugger removes only the odd harmonics from the hum

present in your signal, whereas in Strong mode, both odd and even harmonics are removed. The unit is equipped with a footswitch control for toggling between active and true bypass modes; an LED indicates current status.

True bypass mode

Eliminates hum from any audio source
