Ok, this is just the riff that's played on guitar in the live version (and I think the version) of The Gardener. I think on the album it might be done on a bass, but live Brian Vigilone plays it on guitar. Anywho!!! It's just a really simple little riff that sounds pretty good when played with drums. is literally just e|------------| b|------------| g|------------| d|------------| a|---3-0------| E|---------0--| And that's it! Like I said, it is really simple, but it can sound really effective, and really easy to play!
