Also the VoiceLive Play GTX would fill the bill excellent.
And.... I might be selling mine if I like the VH2 in the S950 enough.
If I sell it, I would ask $250 + Shipping and it would include the TC Harmony MP75 microphone., which is designed for it. It has a dedicated button on the mic to switch off and on the effects.
Won't be getting the S950 until the middle of next week though, so won't know for at least a week if I'd want to sell it.
