I've been playing bass for about 18 years now (god, am I really that old?). I started when I was 16, played for about a year and got decent, then everyone is HS teased me about playing bass because I couldn't play guitar. So I picked up guitar for about a year but bass is my passion so I stuck with bass. I played a 6 string Ibanez bass for a couple years to shut people up about the whole "6 strings too many for ya?". I used to actually care what people thought back then. haha. I had a couple 5 strings but anything below a low D just sounds alien and unnatural to my ears so I stick with 4 strings now. Mostly Fender style. Leo had it right even way back then.
