A cool gimmick but a gimmick none-the-less...still, might be useful for some...

Inspiration is fragile. Remember those songs you lost when you couldn’t record an idea in time, the great riff that came and went, or the computer crash that trashed a fantastic solo?
The Memory Cable™ would have remembered—it’s your personal backup service that runs constantly in the background. This premium, 16-foot cable has a built-in, solid-state recorder designed by TASCAM’s engineers. Plug the cable into your guitar, press a button, and the cable records everything you play. It’s that simple.
If you play something you really like, press a button to close the existing file and start recording a new one. That way you’ll always know your best inspirations are at the file’s end.
Total recording time is over 13 continuous hours with the included 4GB microSD card, but a second mode can record only while you’re playing. The uncompressed, WAV-format files feature 44.1kHz, 16-bit resolution; thanks to the studio-quality A/D converters, if you record a “keeper” you can bring the file into any recording software, then build the song from there.
