Add line-out feature/jack allowing connection to amp's line in

I’ll give it a try.  Funny you mentioned that a nice acessory might be one that takes headphone out and converts it to line out.  As I wrote my first note I had the same thought that it would be nice if such a converter existed since I have run into the headphone  to line-in issue with other set-ups(aside from MP3 connections).
