I've only been playing for a year and a half. But in that year and a half I've become pretty damn good. I'm playing in a modern rock band and we are seriously getting good (badass lead singer). I'll post some links to mp3 files when we're done with our CD for those interested. Anyway, I have a Yamaha RBX460 that has served me well for what I needed up to this point. I just ordered a Carvin LB-70 which I know I'm going to love. Already I'm thinking of expanding my collection. What would you recommend for a 3rd bass? I'm getting better at slapping/popping but I don't get to use it much in the songs we play. Also, should I make the leap to a 5-string? I've always played 4-strings. I'll probably be looking to purchase another bass in 6 months, time to start researching now... Interested in hearing your recommendations and thoughts.
