It's Been A While
Staind

This is the intro riff that is played throughout the song.  I am not sure about the last two notes.  Tune your guitar 1/2 step down.

Eb-------0---------|-----------------|-----------------|-----------------|
Bb---3-------3-----|-------1---0-----|-----------------|---------3-1-----|
Gb-----------------|---0---------0---|---0---0---------|-----0-------2---|
Db-----------------|-----------------|-----4-----4-----|---4---4-------0-|
Ab-0---0---0---0-2-|-3---3---3-------|-------------5---|-5---------------|
Eb-----------------|-----------------|-3---------------|-----------------|


That's it.  I think the chord progression is Abmin/Cb/Gb/Db.
