How do you play like a stone with out a wah wah pedal and still make it sound the same?

That's a good question, he uses a wah-wah during the receding parts of his notes...but you wont get the exact same sound as he does it without a wah-wah. but the best thing you can do to get it close is to do bend and while you're bending the end of the note close it in with a whammy.

buy a wah wah pedal. but even with the wah-wah pedal, it is unlikely that you will ever get close to being able to play like Tom Morello.
