I have two 534's.
One is Makore body with Amboyna burl top, maple neck and ebony fingerboard. Hipshot A bridge.
The other is Ash body with Olive top, maple neck and birdseye maple fingerboard. Hipshot B bridge.
You can tell they both share the same inherent DNA and start from the same tonal palette. To my ear, the Ash body/maple fingerboard 534 is the brighter and more aggressive of the two. It's the better choice for slap style. It is the more open sounding of the two.
The Makore/Ebony isn't really darker sounding, but more subdued might be a way to say it. It is the rounder sounding of the two.
That said, with some tweaking of the EQ they both end up in the same ballpark.
