The same time I learned the opening for "I Just Wasn't Made for These Times," I also figured out the bass part for a section of "Cabin Essence." It should have been obvious just from listening to it because it's only two notes and a common interval (a fourth). I think this is the first time I've used fuzz bass.
Since I last recorded this, I haven't acquired any of the actual instruments used in the first section, so that still has substitutions for banjo, clarinet, and harmonica.
