NOTE: I am primarily a 4 string player that sometimes plays 5 string, but my 5 strings are always tuned E-A-D-G-C (no low B). I never bonded with a low B string (I've tried). Regardless of bass, it has always sounded flabby and undefined to me. Lately I have been watching some excellent 5/6 string players, and I've been paying very close attention to how they use of their low B string. To my surprise, a huge percentage of these players barely use the low B. It's not uncommon to see some monster players that will go the entire tune without hitting the low B string a single time. I'm confused why anyone would use a 5 or 6 string for even one tune, if they weren't going to use the B string anyway. This is an odd, but serious question. Does anyone know why people are doing this? What am I missing? Why are guys doing this?
