Why is it that exotic basses always have more than 4 strings? Let me explain myself for those that don't know what I'm talking about. By "exotic" I mean basses that look really pretty, have active electronics, and in a lot of cases are custom made, not bought at Musician's Friend. I'm talking about MTD, FBass, Conklin, even the Warmoth Gecko only comes in 5 and 6 strings. I don't mean to generalize, I know that some of these luthiers make 4-string basses. But overall I feel that when it comes to custom made, expensive basses, there is hardly any 4-strings. Is this because 4-string players are happy playing their fenders and don't really want to bother with custom made stuff... Any thoughts?
