Some parts sound very synth-like.
I think they’re just doubled. I’d think you’d run into all sorts of problems usability-wise if else was the case.
Looks & sounds like root and 2 unison octaves.
Pretty sure this is a 12 string on this song. Dug has played 8 and 12 string basses, but
I think he has mentioned only using 4 string basses now.
Didn't Tom Peterson use one with Cheap Trick?
Wore that cd out back in the day I knew he had a very unique bass tone but wasn't even aware that more than 4 or 5 strings existed in that time.
