Whether you're a green guitarist or someone who just wants to cut down on the expense and inconvenience of all those 9V batteries, the TC-1S could be just what the doctor ordered. It will be available from selected Tascam retailers some time in October for a little under US$40.

Cool but how useful on a dark stage? :)
I notice there's no mention of battery life either in this article or the product page. I'll take a small clip on with a button cell like the Snark (http://www.barryrudolph.com/newtoys/toys7/snarktuners.html) anyday. These are $15 from Amazon btw.

Why not for home use, stage tuners are a different story entirely of course. That meter doesn't look very appealing to me, though, in the photos.

would be great for camping , tho I wouldn't want to hike very far with a guitar.
