What effect is this?

[Drop-A]

At end of every bar in the intro of Zebrahead - Check


It kinda sounds like there's some harmonic overtones added to a regular fretted note. I've been trying to figure out the effect for a long time now, as it's been used alot in modern (pop) rock.

 

[Drop-A]

Anybody?
I'll throw in another song which makes use of this effect at the intro.
Skrape - Waste


Surely some of you must know what I'm talking about?

 

[Scarpie]

skrape is using a wah.

 

[Ben.Last]

And it sounds like Zebrahead is scraping a guitar string with a pick or coin or something.

 

[Drop-A]

skrape is using a wah.

You can get that effect by using only a wah? I've never used one so I wouldn't know, haha. Thanks anyway.

 

[Bloody_Inferno]

Yeah, the wah filters the frequencies, so you'll hear the harmonic overtones. Plus it also helps using the Bridge pickup and enough gain.

 

[Leuchty]

Yeah Zebrahead is just pick scraping.
