They are both on the same price range and both have seemed to have great reviews from people, yet I bet they´re totally different animals in terms of sound etc... So what´s you opinion?
I don't know that I'd call them totally different animals, or for that matter, any Fenders. To me, all Fenders have a degree of sameness, even ones that are made with different woods and manufacturing methods. Sure, there's variations in tone, but those differences are so subtle that I think they're fairly meaningless in the long run. Let's compare the two you're asking about...the classic 60's is made with alder body and maple/rosewood neck, while the Geddy has alder body and maple/maple neck. The bridge pickup is slightly closer to the bridge on the Geddy, as are pretty much all mid-70's models. These changes will result in a slightly brighter tone than the classic 60's Jazz, but they both still sound exactly like what I consider a classic Jazz bass sound. It's disingenous of me to suggest that it doesn't matter which bass you get, because after all, they do sound slightly different, but at the end of the day, they both sound like a Fender Jazz Bass, and I doubt that anyone else but you will notice a difference when listening to it. I often say that my 98 MIA Jazz is the best sounding Jazz I've ever heard in my life, but in reality, I know that it sounds pretty much like every other Fender Jazz ever made. So to answer your question, I would go for the bass I thought that looked the best. Since I'm not a fan of black, I'd more than likely go for the Classic 60's.
