Are you replying to me? I am aware of the differences is sound and playability between different string types and gauges, generally speaking. I am in the market for a new recording bass, one that has a deep but clear low end like Jazz Basses do, but I'd likd that calrity when playing notes lower than the standard low E. I'm debating whether to get a 5 string with 5th string tuned to low B or to just tune a 4 string to BEAD. I'm concerned about the shortcomings that the Jazz basses have in the low B string, and I'm wondering if those shortcoming swould be the same with said 4 string tuned to BEAD.
