What is the Hum Reducer?
The Hum Reducer reduces the noise that your guitar (or bass guitar) puts out*, including noise that
is caused by electrical interference from your computer display and other sources that are picked up by
your guitar’s pickups. The Hum Reducer will not completely eliminate hum, but it is usually able to
reduce it considerably. To use the Hum Reducer:
Click the Hum Reducer button to light it up red, then •
Click the Learn button, then •
Follow the other directions on-screen in the Hum Reducer window. •
It’s important to position yourself and your guitar in your normal playing position in relationship to
your computer display, etc. when the Hum Reducer is learning the pattern of the noise that it will
reduce. When you change positions relative to the monitor, change guitars or pickups, or add other
possible sources of interference (turning on a nearby television, say), the character of the interference
that your guitar is receiving and transmitting will change, and you should press the Learn button again
to have the Hum Reducer relearn this new hum pattern.
*Note – the Hum Reducer is only available when using GearBox with TonePort or GuitarPort
hardware. It does not appear in GearBox when using any POD X3 or PODxt as the connected
device.
