http://www.ehx.com The Worm from Electro-Harmonix. Tremolo, phaser, wah, and vibrato, all rolled into one. Makes amazing tones...everybody should have one! I like the new version alot better, as they've gotten rid of the hiss/hum of the older version. Plus, it doesn't take up as much room on your board! I used a Strat and a Dr Z MAZ for the clip.
