HUM DEBUGGER

Hum Eliminator

Congratulations on your purchase of the Electro-Harmonix Hum Debugger, Hum
Eliminator pedal. No matter what type of pickups you use or how loud you play, the
E-H Hum Debugger will clean up your signal chain so that hum will no longer
overtake your guitar signal. Simply connect the Hum Debugger to your guitar like
you would any other effects pedal and you are ready to eliminate hum from your
sound forever!

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.

Hum Debugger comes supplied with. Do not use any other
AC adapters. Using other AC adapters, even those made by
Electro-Harmonix, could cause harm to the unit, the
adapter or your drummer. The Hum Debugger does not
use batteries.

-USING THE HUM DEBUGGER-

The Electro-Harmonix Hum Debugger requires no special tricks necessary when 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 should 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.
