There are several ways to reduce the noise picked up by pickups, such as employing noise-canceling pickups or improving the shielding effect of the guitar or bass itself, but all of them change the sound quality of the output from the instrument. In addition, the amount and bandwidth of the required noise reduction can vary, and its effect is often limited. Alternatively, a high-cut filter can be used to make the noise less noticeable, but that will change the important sound quality. We have considered various solutions to reduce noise, and have found that automatically reducing the level of the signal output from the instrument is the best way to preserve both the sound quality and the naturalness of the decay of the instrument’s sound. Turning down the volume with the volume knob on the guitar or a volume pedal – an operation that used to be done manually to make the noise less noticeable, is now performed electronically, automatically, and at high speed.

In developing the Integrated Gate IG-1N, Free The Tone adopted an approach in which the audio signal line is left in the analog domain without being digitized from the viewpoint of emphasis on sound quality, and the output level is controlled at high speed and accurately by a digital circuit. Free The Tone has adopted a digitally controlled analog circuit system which is one of their strengths. This technology is also used in the Free The Tone PA-1Q series (Programmable Analog 10-Band EQ) and Tri-Avatar (TA-2H).

The noise picked up by a pickup becomes more noticeable as the string vibration decays and the volume decreases. The attenuation of the string vibration is not linear, and there are also swells in the vibration, and in reality, while it is gradually attenuating, it is also repeatedly increasing and decreasing in volume. This can cause an unnatural sound at the end of a note when using conventional noise gates. To solve this problem, we have newly developed a signal monitoring function that constantly monitors the input signal by use of a CPU. By constantly monitoring and analyzing the input waveforms, and by performing high-speed control to achieve an optimum output level based on the waveforms, we have succeeded in obtaining natural attenuation.

The most difficult issue was how to minimize the sound quality change caused by passing through the Integrated Gate IG-1N. Ideally, there should be no change in sound quality when the Integrated Gate IG-1N is connected. In order to convey the true sound of guitars and basses to the equipment connected after this unit, the circuit through which the audio signal passes is a completely analog circuit, and Free The Tone spent a great deal of time examining and perfecting the sound quality. You will notice that its sound quality is fundamentally different from that of conventional noise reduction devices or noise gates.
