Question about Trey's live sound

I’m wondering if you guys can help me determine what effect Trey uses in alot of the 95-97 shows I’ve heard… For example, at the denver '97 show, take the tweezer for example, he’s running through his tube screamers, wah and there’s another effect (probably multiple) but it gives his distortion a nice dynamic sound… its all over the tweezer…
Another example off the top of my head is the chalkdust from 10/21/95… again, not just straight distortion, but a chorusy (kindof) type of effect as well.

Sorry for the shitty description… not exactly easy to do. I’ve been checking out www.strangedesign.org and looking at Trey’s rig, but the descriptions haven’t helped me much.
Anyways, thanks for the help

Part of Trey’s signature sound from then was the Ross compressor. Not sure if he’s still using it. All I know is they’re out of production and extremely hard to find these days. Anyway, that may be what you’re referring to.
