A Guide to Guitar Effects

How to Categorize and Order the Boxes in Your Signal Chain
By Jon Chappell

Most guitarists have an intuitive sense as to where basic effects should go in their signal chain. If you have two pedals, a distortion unit and a digital delay, you would naturally put the distortion before the delay (the guitar goes into the distortion, the distortion into the delay, and the delay into the amp). But the more pedals you use, the trickier it gets, and some truly bizarre gizmos—like a digital whammy pedal—might put you at a loss to explain just effects go where they do relative to others in the chain.

Additionally some processors (such as EQs and reverbs) can go in different places in the chain, depending on the desired effect. And in one very famous example, the debate is still raging about whether the wah-wah goes before or after the distortion (Hendrix put his before, though conventional wisdom says the wah should follow).

Now, you might be thinking, "Gee I know in which order the basic pedals should go, but I guess I don't really know why."

Before we discuss which categories of effects go where they do in the chain, take this pop quiz (I hear you groan) to determine your effect-ordering mettle. Order the effects below from 1 to 10, with 1 being the first effect the guitar plugs into, and 10 being the effect whose output goes into the amp. No text-messaging among yourselves for hints.

1. __ A. EQ
2. __ B. Distortion
3. __ C. Chorus/Flanger
4. __ D. Noise Gate
5. __ E. Digital Reverb
6. __ F. Volume Pedal
7. __ G. Preamp
8. __ H. Compressor
9. __ I. Delay
10.__ J. Wah-wah Pedal

Here are the answers, showing the "correct" order of the 10 effects above: 1) G, Preamp; 2) H, Compressor; 3) B, Distortion; 4) J, Wah-wah pedal; 5) C, Chorus/Flanger; 6) I, Delay; 7) A, EQ; 8) D, Noise Gate; 9) F, Volume Pedal; 10) E, Digital Reverb.
