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
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 PODxt as the connected device.
