This could be posted in both the EB & DB forums. But with my six EBs and two DBs the A string is always "unique"... Sometimes "chourusy" or clacky or buzzy or whatever, but almost always different than its EDG brethren... (And I've used many,many different strings on both) I understand the ol' 440 is the standard. But the A always seems different. Is it music theory, physics or an act of god? Preemptively I'll give you, I might just be crazy... I really would be interested to hear from those who might know more. Thanks!
