Jazzyvee,
I don't think my comments are at odds with Mica's comments. In general, the electronics in Alembic instruments sound vastly different from non-Alembic instruments. And that difference completely overshadows the differences between woods within a particular Alembic model.
If you were asking about an instrument with a single filter and fixed Q versus a Series instrument, then I would have said the Series electronics were WAY more flexible. But you are asking about two instruments that both have dual filters with switchable Q. And while working with volume/blend is somewhat different from two volumes, I don't think that really affects the sound. So my comments about the wood making a big difference was within the very narrow confines of two instruments with very similar controls.
I had two Rogues with different top wood (Wenge vs Walnut) and all the rest of the wood was the same. With the controls set the same (Q off, filters open), there was a discernable difference between them. That difference was very obvious to me, but not to anyone else in my family. However, they could all tell the difference between them and my Fender P-bass! For me there's also a huge difference between the wenge Rogue and my coco bola Series II. On a good day some of my family could tell the difference...
And while there's a difference, I don't consider it a better/worse quality thing, but rather a difference in character - blue isn't a better color than yellow. So I would say my Series has a huge, round sound and the Wenge Rogue had a snappy, aggressive sound. My take on that is the ebony in the neck and coco bola body in the Series versus the all maple neck and Wenge body in the Rogue, not the difference in electronics.
That said, if someone offered me a free upgrade from Signature electronics to Series electronics, I most certainly would accept!
