In addition to the one Gary mentions, if you search ring exchange for my username, you will find a pedal control Talkbox Rig and a touch controlled Talkbox Rig.
GS FRAMPTON - DR is the one I mentioned (since tweaked some more). I couldn't find Paul's just now, but I've downloaded them as well. They all have their plusses and minuses but they're also pretty good! I use mine for Frampton and Rocky Mtn Way. They go over really well.
