In response to a question about why the low pass filters on Alembic basses have a top end limit of 6KHz, Nic discusses string vibration, pickup placement, pickup electrical response, and Q switch boost. It's a really nice explanation of the significance of the 6KHz limit; and it can be found
here.
Further down that same thread Nic has a nice
historical post. And then a little further down from there, Bob has a
detailed response to Nic's first post delving deeper into the topic.
