Chris beat me to the link...
You can input "tuning" in the search box and get several more tunings for other type of guitar styles..
For around $25 you can get a desent electronic tuner does acoutic electric and bass tuning... I have my step-daughter tuner that is a MUSEDO, which is combine with a metronome.. Cool tool to have in your gig bag..
Good luck and keep on pickin'
