Oh, that reminds me. The empeg's inputs are probably not ``tuned'' to accept a line directly from a guitar's output. The guitar would be way quiet, as the only electricity actually being generated is very minimal. I think that alone would probably make the empeg unable to properly determine the note being played. And I'd imagine that getting something that would provide enough power to make it work would cost as much as just getting a tuner. (Hell, for $20, getting an adapter for a 1/4" phone jack to an RCA jack would get you close.)

But I could be wrong.
