Here's a "free" guitar tuner that I recently created. It is a flash file, has an incredibly user-friendly interface, takes less than a minute to download and best of all, it's free. Another great and unique feature of this tool, unlike other simple 6-string tuners, is that you can tune any string to any note you want!!! Get it by clicking the icon below:
*Note: This has been added to the "Misc" tab/page too.
