Ah yes, I remember your commentary on the subject from other threads now. I think the term I've heard used for preferred bass tone is "Dub". I can see where dual filters, even mostly closed would be a bit conspicuous, sonically.
It's interesting; the music genre' I played in, at least the traditionalist element of it, was completely intolerant of a bass guitar at all. I've been fortunate enough though, to play music with some people who just let me be me, trusted that I knew what and where to play. What do you know - you can play string band music on an Alembic. Like you, I just had to find my place in it, using my preferred instrument.
Hopefully there's a simple workaround for you here.
