Noise is a definite no-no in many situations. For example, studio etiquette demands
that you keep a lid on extraneous noise during short breaks. It's in the nature of high-
gain rigs to generate undesirable peripheral noise in overdriven channels. This is
attributable to the physical properties of an amp's constituent components, in
particular its active components. That's right; those cherished tubes are the culprits.
The Noise Gate is a tool that lets you silence this noise during breaks by way of signal
mute circuit. Note that electric guitars pick up interference signals, and these are
amplifiedtremendouslyathighgainlevels in Lead mode. The mostcommon source of
noise is 50 or 60 hertz mains hum, particularly when the guitar is positioned near
transformers and power units. Because in worst-case scenarios this humming can
attain extremely high levels, the Noise Gate can hardly distinguish between the
musical signal and noise. This makes it hard to find the right Threshold setting. It is

Press this button to store the modified setting of a programmable feature to a MIDI

The preset programming process -- the Write command, that is -- is not carried out as
soon as you press the button. Pressing the button merely initiates the process. You

You'll have to go through a similar routine to copy a preset once you select a target
