Drop D tuning is one of the simplest alternate guitar tunings, and it can also be the most effective allowing for simple bottom-3 power chords. The trouble with the drop D style of tuning (lowering the bottom E string down to D) is that with most normal, electric guitar strings, you might lose some definition in the tone due to lack of tension. With these premium quality nickel-wound strings from Newtone, the bottom sixth string has a thicker core, so it retains its tonal quality. Available in three different gauge sets, these premium strings will give you a clean bottom end and rich tone. They're ideal as drop D slide guitar strings for a rich, full sound.
