Hi David,
Thanks for the compliment! My other basses are Rogues and Essences - I don't own any Europas - YET!
As for the Vermillion Excel, the controls are still pretty basic - Bass, Treble, Volume and Pan. The sound as you can imagine is bit fuller than my standard Excels. I can get a little more ringing harmonics on that bass, as well as a sweeter mellow tone when I lean on the front pickup. I LOVE playing Jaco's Portrait of Tracy on that bass. Great punchy tone, and harmonics that go on forever. As much as I love the standard Excel, this one has that little extra dimension. I found that bass by luck; just walked into my local music store and there it was! I don't know if Alembic made many more like that, but it impresses the heck out of me each time I play it!
By the way: I traded a Music Man Stingray 5 in for that Excel. One of the best moves I ever made.
Good luck,
Rami
