For me, the trick was trying to replicate that type of tone on a bass - or going another route altogether.
I first ran through it a few times on my Peavey TL-Five, the bass I was going to play for the rest of the P&W set. It would've worked, but the attack on each note really didn't feel right. I tried the fretless. As a band, we could've made this work, but it would've changed the feel of the tune, unless I just played it straight. In that case, I would've just played the fretted bass.
