I have a Line 6 M9 and I want the voice box effect to get me really close to a talk box. I need it for one song and I don't want to invest and lug around a talk box for 3 minutes of a 4 hour show. So I need to get relatively close to a talk box sound from the M9. I have searched and searched and the closest I found was a HD500 patch, but it wasn't really cutting it. Right now I'm using a nasally wah kind of setting, but I'd love to know what the Line 6 M series users are doing to get a talk box vibe. Even a combination of pedals or patches is OK is it's convincing. Whatcha got guys?
