My mother always says that you have to crawl before you walk. Please buy a 4 string and learn the fundamentals of your instrument. If, after a period of time learning fundamentals, you are ready for the jump to 5, then by all means..... I know a cat who's just starting out, and bourght a five-string! And I met a cats who played a Ken Smith Burner 6, and had only been played for ONE YEAR!!!!!! Just remember, you must learn 2+2 before you get to calculus! Peace.
