With luck my Earnie Ball light guage go back on my guitar tonight.Instaed of using my cheap $30.00 Yamaha needle 440 tunner I would like to try something more exact on line if there is such a thing. Have heard there are all kind of free downloads out there that claim to work.. Can someone give me the download to one that works well but doesn't add a bunch of junk to my pc causing trouble with it down the road or pop-ups trying to sell me more garbage I don't need? Just want to do the basic tunning and drop-D down the road if your program has this function and tell me how to get to the drop -D with this program so Ican take a look for the future. Big thanks in advance.-Rob
