I too bought the Line6 G50... I paid $299 (AMS)... "demo/scratch and dent" model...in PRISTINE like new condition with warranty. I've never used wireless before...and I'm not tech savvy. I plugged it in and went... absolutely idiot proof... and it works AWESOME.

The only thing I modified...was I took the plug-in jack that plugs into the guitar and I went to Radio Shack and had a low profile flat plug put on so that it is almost invisible...and there's no jack sticking out now to catch on anything...other than that it's stock. The unit is small... and from what I was told, of all the brands, it is the ONLY one designed by actual guitarists....instead of some non-musician tech engineer. (?)

I use ultimate lithium and Duracell Duralock rechargeable NiMH batteries... and get around 8 hours play per charge...or disposable... the lithiums are SWEET, but not rechargeable :-( . The batteries don't just poop out on you there is PLENTY of warning with the three light system. The unit is small enough that it actually fits in-between the folds of my guitar strap and is nearly invisible. I LOVE IT. (great Xmas gift for that musician in your life)

I hope someday to actually get to put this to use on a stage...
PEACE
