Recently ive been attempting to replicate the sound of a speeding vehicle going by and changing gears with my guitar. I've seen some of my other band mates do it and our lead guitarist does it perfectly. If you close your eyes it really feels like a turbo charged vehicle is driving right inside the room.

To get this effect I dropped D tuned my guitar and hit a power chord WITH the whammy bar DOWN and slowly pulled it up and let the distortion rip through.

Once the whammy bar was all the way up and reached its top sound; I simulated a gear shift by simultaniously, pressing the whammy bar down again, and sliding up 4 frets and then sliding down 6 frets really fast, so that i was 2 behind the one i started at.

I then play the power chord 2 frets below the first with the whammy bar all the way down again pulling it up and repeating the process until i reach the end of the fretboard.

While this sounds slightly confusing I got a roaring sound that sounded awesome. Trying to get effects like this is somthing i do on a daily basis. Anyone know of how to acheive this effect even better. Thoughts comments etc. I'll post a sound file soon.
