I just started thinking yesterday, while pondering the headache that is background noise, why don’t all amps include a built in noise gate? You’d think, with modern technology being what it is, installing a built in adjustable noise gate would be as basic in all amps as a power cord. A standard feature. I mean, come on Fender. My $5.99 Garage Band app has a great built in noise gate as one of its many features. Why can’t you guys get with the times? Including one wouldn’t hurt the overall voice of the speaker one bit. The cost would be minimal, particularly in such modern amps as the tonemaster series.
