Noise Gate - A Noise Gate is a barrier that will close when you are not playing, and open when you are laying. When the gate is closed, it will not allow ambient noise to come through. A noise gate uses a threshold, hich is the volume level required to open the gate. If your guitar signal is not strong enough to cross the hreshold, the gate will not open, and no sound will be heard. The gate on the GS30 is also used for volume wells. When you have selected the gate to act as a volume swell, you can strum your guitar, and the sound will de in. There are 10 Gate Threshold settings (1 - 10 with 1 being the most sensitive and progressing to10 equiring the strongest level to open), and 5 Auto Swell settings (A1 opens with a weak signal and fades in uickly, progressing to A5 requiring a stronger signal and fades in slower).
Chorus - A Chorus is an effect that adds thickness to your guitar signal. It is splitting your guitar signal, adding short delay to one of the signals, and then changing the delay time at an even rate. This results in a slight uctuation in pitch of the delayed signal giving the thickness of two guitars playing together.
Flange - A Flanger is similar to a Chorus as far as what it is technically doing, but it sounds very different. It dds a “whooshing up, and down” sound to your guitar by incorporating regeneration into the delayed signal.
Phaser - A Phaser is an effect that splits the incoming signal, and then changes the phase of one of the signals. his phase is changed at an even rate, and mixed back in with the original sound. The changing phase mixed with he original signal causes different frequencies to be canceled, resulting in adding a warm, twisting effect to your nstrument.
Tremolo - Tremolo is an effect that modulates the volume of your guitar up and down at a steady rate. The remolo offers two selections of wave forms: triangle and square wave. A triangle wave form is shown as tr in he display and is smooth. A square wave is shown as re in the display and is more abrupt.
