Distortion provides a wide style range, and all styles serve for spicing up the sound mixture. It is also often combined with compression and overdrive.

Frequency Effects

Modulation Effects

Tremolo and Vibrato

Tremolo modulates volume for a classic rockabilly and surf effect, while vibrato modulates pitch in the same way with a Leslie speaker.

Chorus and Flanger

Flangers create a movable filter by the double signals. It modulates the delay of these signals, so the shifting of the filter happens.

Even if it is a bit, you can have a little delay signal feeling in the effect. Besides, the flanger includes the modulation rate and depth.

Time Effects


This effect is based on the original signal and repeats it multiple times. Nowadays, you can make many styles of multiple delays or delay lines to create an impressive effect range.


Reverb contributes to creating a space-around-sound feeling. The common use of this effect includes the decay effect, wet or dry balance. You can adjust them up to how much reverb you want.
