Internal Design of the DTX700  Flanger & Phaser A flanger creates a swirling, metallic sound, similar to that of a jet plane. While this effect operates using the same basic principles as chorus effects, it uses shorter delay times and also incorporates feedback to produce a very distinctive swelling sound. Rather than being used constantly throughout a song, it is more suited to selective use in specific sections in order to add variety. A phaser, meanwhile, introduces a phase shift into the sound being processed before returning it to the effect input using a feedback circuit in order to produce a characteristic animated yet mellow tone. Gentler overall than a flanger, this effect can be put to use in a wider range of situations, and for example, is often used with electric pianos to sweeten their sound in a variety of ways. Effect Type Cho Var Description SPX Flanger   Produces a swirling, metallic sound. TempoFlanger   Tempo-synchronized flanger. PhaserMono -  Vintage sounding mono phaser. PhaserStereo -  Vintage sounding stereo phaser. TempoPhaser -  Tempo-synchronized phaser.  Distortion As its name suggests, a distortion effect distorts the sound fed into it. It produces a sound similar to that of an amplifier turned up too high or fed with a signal that is already sufficiently loud. This type of effect is widely used to add a harsh, biting edge; furthermore, the resultant sound is characterized by overall thickness and long sustain times. This thickness comes from the large numbers of harmonics contained within clipped signals. Meanwhile, the longer sustain is not produced by the original sound being stretched; rather, it is produced when the slowly-fading release portion that cannot normally heard is amplified and distorted.

Auto wah changes the frequency in a cyclic manner using an LFO, while touch wah performs filter sweeps in response to the volume of the input signal. Effect Type Var Description AutoWah  Vintage automatic wah effect. TouchWah  Classic volume-responsive wah effect. TouchWahDist  Touch wah with distortion applied at the output.  Reverb Reverb effects model the complex reverberation produced by sounds within enclosed spaces. In this way, they add a natural-sounding sustain, which produces a feeling of depth and space. Furthermore, different types of reverb - such as hall, room, plate, and stage - can be used to simulate the sound of acoustic environments of varying sizes and constructions.
