How do I get that post-grunge sound on my guitar?

Disclaimer/Disclaimer II - standard tuning and 1/2 step down (drop-D) Karma and Effect - recorded using baritone guitars tuned up (which you shouldn't do because it's not good for the guitar) to mostly drop-D 1/2 step down with a few exceptions. ("Given" was written in drop-D 1 and 1/2 steps down... so BGCFAC#). On a side note, Seether used Marilyn Manson's guitars for the recording. Finding Beauty In Negative Spaces - written mostly in drop C. Holding Onto Strings Better Left To Fray - mostly in drop C. Buy Ernie Ball Cobalts to get a thicker sound, and use a heavier gauge. Technically, you'd need a Mesa head to get the exact sound, especially a triple rectifier, but you should be able to easily emulate a sound like it using a line-6 Spider amp or a POD. With the amp, if you know how to rewire things, you can remove the middle of the three prongs from the headphone jack, re-route it to a switch, and run a secondary amp out of it to get an emulated sound simultaneously, adding a little more of a high-end gain to the mix. Clean, use light reverb and slight tape echo. Guitars, go with any Schecter model that has a push-pull tap for single coil pickups. Mahogany wood, rosewood fretboards, and maple necks seem to have a similar intonation. As for chords, there really isn't any model. Most post-grunge bands just use variations of power chords. Look at the Foo Fighters. They have three guitarists to create a wall of guitars. Seether and Chevelle frequently play octave chords (that would be like a 5 on the A-string and a 7 on the G-string.) Hope that helps!

Spit on the guitar.
