The Gig-FX Mega Wah is 5 individual killer effects:

A classic wah plus adjustable filters and EQs to get the sound of your choice from a cry to a throbbing deep wah that can give a guitar the funkiest, heaviest wah you can imagine.

An auto-wah with controllable frequency. Set the wah to the tempo of the song and wah away rhythmically with no effort.

A trig-wah triggered by a note—play a note and it wahs—no foot effort required—for fast licks, this is an unbelievably funky sound.

Innovative stereo wah. Stereo in and stereo out—it wahs in unison on both sides—twice as much wah-appeal—but then—REVERSE the wah on one side so one side wahs while the other side "haws," so to speak. It's like a chorus on stereoids!

A volume/gain boost pedal with up to +12dB of gain, controllable by the volume pedal.
