Hello everyone. I've been building guitar effects pedals and such on an off for a couple of years now. I work in sales and am in need of an audio interface for my telephone to be able to output from, like this one:http://www.turneraudio.com/jkaudioquicktapifb.aspx
I don't know how phone wires correlate to regular audio, but I do know would like to build this little interface for significantly less than $120 I can buy it from these guys for. Can anyone lend help or refer me to a schematic so I can built a similar unit? Thanks!
