I have played guitar for many years and only experimented once during this past Spring with alternative tunings. Are there any great sites where one can dip their feet in, get some chord charts and try some well known songs to see how they work?
Check out Kyser K-Lever series of Partial Capos. They put a standard tuned guitar into alternate tunings without retuning the guitar. There are four different color coded capos.

All have the K-Lever which Premier Guitar Magazine described at "pure genious".
