Section 7: Reference
7.1.2 WAH EFFECTS
No other effect defines the era of “classic rock” better than the WAH. This effect single-handedly turned many
guitarists into Guitar Heroes. The FX770 features not one, but three great WAH effect Types. All of the WAH effect
types may be controlled by your foot (via the WAH foot controller input), by sensitivity (guitar input), placed in a
“-fixed position or be set to become an Auto WAH (LFO).
Type 1 & 2: WA1 (WAH 1) WA2 (WAH 2)
Both WAl and WA2 are band-pass filter type wah.
WAl simulates a classic wah pedal, and WA2 has a wider frequency band.
