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

amplified tremendously at high gain levels in Lead mode. The most common 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

entirely possible for this humming and other noise to rise to a level that deactivates the

and therefore becomes audible. My advice is to stay as far away from

transformers and power units as space allows.

: The

may open up inadvertently

when the

is activated, a high-gain Lead channel is selected, and the volume

exceeds the Threshold knob setting. At very high volume and gain settings, this may

generate instant feedback, particularly if your guitar is facing the speakers. Rather

than musical and controlled, this is the shrill, unpleasant and potentially harmful

variety of feedback squealing that sends your audience and fellow musicians packing.

Though the amp is not more susceptible to feedback when the

is activated,

the fact that it suppresses extraneous noise means you can't hear those telltale signs

that feedback is swelling and consequently can't take measures to suppress it. For this

reason, make an extra effort to be careful when the

is activated: Before

you approach the amp and speaker cabinet with your guitar in hand, turn the guitar's

volume knob to the far left position (to 0 so that no signal is audible) to prevent the

pickups and speakers from interacting!

Connect this FX Loop 1 output to a signal processor's input/return jack using the

shortest possible shielded cord equipped with 1/4" plugs. Activate and deactivate it via

the FX Loop 1/2 (13) button, which switches between these two loops. In the signal
