Description

Electro Harmonix Hum Debugger

Absolutely eliminates hum from any audio source. Not a noise gate and not a suppressor. Dead silence in your signal chain courtesy of a little EH magic.

• Power Supply Included

NORMAL/STRONG TOGGLE SWITCH – Sets the amount of Hum Elimination. In NORMAL
mode the Hum Debugger removes only the odd harmonics from the hum present in your signal.

In STRONG mode the Hum Debugger removes both odd and even harmonics from your signal’s hum content.

STATUS LED – When the LED is lit the Hum Debugger is active. When the LED is off the Hum Debugger is in True Bypass mode.

FOOTSWITCH – Toggles the Hum Debugger between active and True Bypass modes.

CONNECTIONS – Connect your instrument to the INPUT Jack. Connect your amplifier or the rest of your effects chain to the AMP Jack.

POWER – Plug the barrel connector from the AC Adapter that came with your Hum Debugger into the power jack at the top of the Hum Debugger. Plug the AC Adapter into a solid wall outlet. You must use the AC Adapter that the Hum Debugger came with and the AC Adapter must have an output of 7.5VAC with the ability to supply at least 200mA of current.

Using the Hum Debugger

The Electro-Harmonix Hum Debugger requires no special tricks necessary to remove
hum. You can use it like you would any other effects pedal. The only thing to remember is you must use the AC Adapter that the Hum Debugger comes supplied with.

When using the Hum Debugger first set the toggle switch to NORMAL mode. NORMAL mode should work well in most situations. If you find that the Hum Debugger is still letting some hum through then move the switch up to STRONG mode, this will remove the rest of the hum.

If you use more effects pedals than just the Hum Debugger we advise that the Hum Debugger be inserted at the beginning of the effects chain.
