Hi Marco,
I can only give you my opinion based on my experience.
I have an Excel with a Pau Ferro fingerboard and I love it! Granted my bass is only a single pick-up so I can only tell you that it gets great low b's massive you might say from my fat boy pick-up. It's got the best fat low sound I have ever heard. It is so thick and low!!!!
In as far as I can tell ya about bright, it's crisp and clean and yes deep tone as I eluded to earlier.
Actually I was just reading up on it and would even consider putting it on my ordered Series II but I already have Ebony ordered and so I am going to stick with that.
But honestly, I bet there isn't that much diffence between it and Ebony, if anything it might even be better depending on the application. Ebony probably is more dense though. Although Pau Ferro is known as Ironwood!
I say- Go for it!!!!
Aloha, Paul
