The wah-wah pedal is based on a simple concept but its effect is far more dramatic. Using a powerful filter to sweep through a broad frequency spectrum, the wah pedal boosts and exaggerates specific tones. Creating sounds that range from thick, flubbery bass to scratchy, stinging treble.
What the 'Wah' does is that it changes the Bass to Treble-or vice versa, depending where your at-on the press of a pedal, and the flanger takes a little time. There is slow and fast Flanger, but the Flanger cannot make the ' Wah' sound. With Tremolo, these two effects combinded will rock. Songs that have Flanger: Blink-182 - Obvious-the verse-, Asthenia-when the guitars some in, verse-, Here's you letter-intro-, Feeling This-intro, even percussion have flanger-.
