thanks for the replies philmusic guys, its good to know some people tuned their guitar in variety of ways. I am just a self taught guitarist nothing more than chords, tabs and others. Its just now that I started learning theories (self taught actually) and id like to know if its bad learning guitar theories in Eb, will it affect my learning? Or will I tune it to standard while learning guitar stuffs. Also thanks for posting open tunings here and stuff I will try those.
