It's interesting you say this, Jake... I've had the very same thought, and was considering starting a thread on the subject (but obviously, you beat me to it).
My other custom Alembic -my 8-string- has definitely improved it's tone over time... but it really seems like there's been a dramatic improvement in the tone of my new MK6 deluxe with Coco Bolo front and back in the short time I've had it. As with yours, it sounded great the first day I had it... but it seems to have really gotton much better sounding in just a few short weeks. No doubt about it... very noticable.
Mica has stated to me and to others, on many occaissions, something to the effect that it takes time for the wood(s) to realize they're an instrument; it takes 'em a little time to get settled in their new role.
The tone of my new MK6 Balance K Signature Deluxe seems to have become more crisp and defined after a few weeks... it has a very complex tone from the combination of 6 different woods (including the Coco Bolo, of course), and I've found it's become more easy to hear the individual components of the sound. The Vermillion is the only one I can't pick out... I don't know the sound... haven't really heard it before... and it's said to sound similar to Mahogany, so it probably just blends in with it. But I can clearly hear the other 5 woods individual aspects/contribution(s) to the sound.
Of course, I've also become more adapted to and familiar with the instrument as well.
Hopefully, it will continue to improve!!! Of course... it's already EXCEEDINGLY awesome!!!
