  • Page 4: About The Guitarfx, Guitarfx Basics

    Introduction About the GuitarFX The first thing you’ll probably notice about the GuitarFX is its size—it’s not that much larger or smaller than most other guitar effects pedals. But don’t let that fool you. The GuitarFX does much more than most pedals you’ll find on the market today (and for an unbeatable price too).

    Effect Modules If you were to think of the GuitarFX as a series of individual pedals linked together, then each pedal in that series would be considered an effect module. The GuitarFX has nine separate effect modules, as shown below: You can assign one effect to each of these modules and adjust its parameters accordingly.
