I think it's the Ibanez AF 9, but I can't find any proof that Weir used it. The Ibanez UE 400 also apparently had a wah feature but I don't know if Bob was using his in the 90's, my guess is he wasn't. Ibanez made several auto filters over the years so I don't know if the AF 9 was the one Bob had or not.
The UE400 doesnt have a wah feature it has a compressor, phaser, overdrive (or distortion depending on version), flanger/chorus.
It could have been an AF-9,Bob did use one off and on.
It also could have been the custom Cutler Pedal that he had in a Wah case which was a combination of a Phaser and a Wah (The sweep of the Phaser was foot controllable)....however it doesnt sound like he was using his foot to rocker a pedal while he was singing, it sounded more like an auto-triggered effect.
Also it really could have been one of 100
different things. It is very, very hard to tell...so without asking him (and he probably wouldnt remember anyway

) we can just speculate.
For sure it would be pretty easy to get in that ballpark using an AF-9, some distortion and some compression,
