I think you would like the Ibanez Tube Screamer, it's Eddie Van Halen's pedal of choice.
Tube Screamer rocks. It's my favorite. I guess I'm gonna be the next Eddie Van Halen.
I like my Boss RC-20XL Loop station. It's fun to play around with. You can lay 11 loops down at once. The best feature is that you can change the output level so your loops don't dominate anything you're playing. It's great. I bought it when I was in a three piece band and it filled in the gaps nicely.
Other than those, I just use my Crybaby 535Q, a vox volume pedal, and a Boss CS-3 Compression Pedal.
I like to talk pedals....I went pedal nuts a while ago. I bought everything I could afford. But now I'm down to those. A man can get too fancy IMO.
