First off, I'm not new to music. I'm just new to bass. I am fairly experienced on keys and I am comfortable with theory. Fortunately, I can buy a quality bass (Warwick Corvette or Thumb ) and I don't want to have to upgrade later. Is it too difficult to begin with a 5 string? Am I making a stupid decision? All opinions/experiences will be appreciated from newbies and vets. Thanks!
