Congratulations, sweet bass, should give you years of sonic bliss! The Alembic basses with a filter really benefit from having a Q-switch installed, you might consider having that done at some point. Without the Q-switch there is always about an 8dB boost at the selected frequency on the filter. The Q-switches come in two different configurations both allow you to select no boost which can be used to mellow out the attack and give a rounder tone, generally the three-position switch is the way to go and the most versatile... following info from the Alembic site.
"For Essence basses or any Alembic Activator system with a low-pass filter.
This prewired switch replaces a single box capacitor on the AE-1 preamp board. Once installed, it allows you to have the familiar 8 dB boost the filter always offered PLUS the option to dampen that boost to near zero for the flat filter response. In a nutshell, if you want to have access to tones with less attack than you have now, you need this simple modification.
After adding the switch to the board, you'll need to drill a hole in the bass, and possibly recess it. It's best if you are able to shield the newly recessed area.
Mounting hardware and instructions are included.
Also available as a 3-position switch with settings of approximately 0/6/9 dB. Select option for number of positions and bass or guitar below."
One thing I was curious about with your new bass, though. The build sheet indicates it has purpleheart in the neck but I am not seeing any in the pictures you posted. Usually that refers to the laminates that run the length of the neck, you can see them clearly in the picture of the five-string Spoiler in post #15, your neck seems to be all maple.
