"Very few people choose to play Bass. There are people in the audience who like to listen to the Bass, because they like those low frequencies, and the way they make their bodies feel -but the role of the Bass player in the band is not usually the most exciting role, because he has to play repeated figures. We have a viola parallel here: electric Bassists are often failed guitar players, demoted to this duty after a band meeting in a garage when hey were thirteen."
Frank Zappa (excerpted from his 1989 book: The Real Frank Zappa Book, Poseidon Press, Chapter 8 All About Music, Section: The Anthropology of the Rock and Roll Band, pg. 164)
With all due respect, Frank Zappa can kiss my ass.
I took up the bass in April of this year after wanting to learn to play for literally decades. I do not play guitar. I have never played guitar. I have no immediate plans to play guitar because I've never wanted to play guitar.
My neighbor who is an excellent guitar player told me that good bassists are always in demand because the ratio of bassists to guitarists is about 100 to 1. I don't know if that true or not, but I don't really mind because I've never had the desire to stand up in front and shred.
