Anyone know that slidepiece on the end of the 2nd part of the intro riff to "Loser" by Smile Empty Soul? The song is in Drop D, 1/2 Step Down and I know the 3 chords before it, because the band themselves told me. I forgot to ask about the 4-note slidepiece at the end and I can't make it sound perfect. The closest I can come is:

4/5--4--1 on the D string.
Nevermind, figured it out. I tabbed the intro if anyone likes this song, and I will include the slidepiece as soon as I can edit it.
