I am a bass player of exactly 11 days and it took me less than two weeks to realize whoever invented the elctric bass was a nut. A more difficult instrument could not be made.
When I first started playing guitar I chose a favorite Beatle song to learn - "Mother Nature's Son." In one weekend I had that complete song down. From when I first picked up a guitar it only took four days to play that song in full. Not only did I play it, but I tweaked my amp and had my Fender Strat sounding exactly like Paul's acoustic. Perfect.
With bass I chose my favorite bass song - The Beatles' "Glass Onion" - and it is damn hard to do. The notes don't flow like they do with my guitar playing, and the sound I get can not duplicate what I hear on the record -- and I am playing the exact model Paul played on that tune, the Fender Jazz. With guitar I can make a Fender Strat sound like a Martin acoustic, but with bass I can't make a Fender Jazz sound like a Fender Jazz!
Why is bass so difficult? The required dexterity is a million times greater than guitar; and the perfect sound (flatwounds, roundwounds, what gauge, pick, slap, fingers, amp...) is elusive as hell.
Just a rant. Maybe I should have bought a sitar...probably a million times easier to play.
