I'm not sure exactly how you want your wah-wah effect to appear, but for starters you can go here:
http://lilypond.org/doc/v2.13/Documentation/notation/the-feta-font#index-Feta-font ...to find the glyphs you need. The ones you need are listed under "Script glyphs." One is "stopped" (looks like '+') and the other is "flageolet" (looks like a small circle). There is also "open" which looks like a small letter 'o'. I've normally seen the little circle (I'm a trombonist). I don't know how to do this without experimenting with it but if you want '+O' I suppose you could create a script called 'wah' or something and combine them together side-by-side. This would mean 'wah' on a single note. If you wanted the effect to span two or more notes I think you should be able to put the '+' over one note, the 'o' over the other and put some sort of dotted/dashed spanner between them.
