Internal Design ● Wah A wah effect dynamically changes the frequency characteristic of a filter in order to produce a highly unique filtersweep sound. 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 AutoWah TouchWah TouchWahDist VAR Description ✓ Vintage automatic wah effect. ✓ Classic volume-responsive wah effect. ✓ 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.

As all instruments differ slightly from each other in terms of pitch and phase, their playing together produces an overall sound that is warmer and more spacious. In order to reproduce this type of behavior, chorus effects make use of delay. Specifically, a delayed, second version of the original signal is produced and given a vibrato-type effect by varying its delay time over a period of approximately one second using an LFO. When this second version is mixed back into the original signal, the resulting tone sounds as if multiple instruments are being played in unison. Effect Type G Chorus 2 Modulator SPX Chorus Symphonic Ensemble Var Cho Description ✓ ✓ Rich, deep chorus with complex modulation. Chorus effect allowing pitch and ✓ ✓ amplitude modulation to be adjusted for a more natural, spacious tone. ✓ ✓ Enhances modulation and spaciousness using a 3-phase LFO. ✓ ✓ Multi-stage modulation for a widersounding chorus. - ✓ Modulation-free chorus achieved by adding a slightly pitch-shifted sound. ● Tremolo & Rotary Tremolo effects are characterized by the way in which they modulate volume in a cyclical fashion. An auto-pan effect, meanwhile, moves the sound from left to right in a similar cyclical manner, and a rotary speaker effect simulates the distinctive vibrato of rotary-type speakers often used with organs. In a rotary speaker, the horn and rotor are spun in order to create highly unique sounds using the Doppler Effect. Effect Type AutoPan Tremolo RotarySp Var Description ✓ Cyclically moves the sound between left and right channels. ✓ Cyclically modulates the volume of the processed signal. ✓ Rotary speaker simulator. 38 Owner's Manual
