I just got a second hand bass, it is a Yamaha SuperBass 800. the bass is about 2 maybe 3 years old i think. the person who owned it before said the action was alittle high. how do u tell if it is. and how do u read tabs for basses. Can any1 tell me if my bass is any good. i traded it for my Vantage Acoutistic Guitar that is 3 years old. Did i get a good deal?
