Keep in mind that natural finish will age and get darker over time, walnut finish will lighten to a caramel color, and the darker finishes (especially ebony) show scratches and nicks much more. The finish on a LH harp does take years to change color, though. Also, with ebony you can’t see the wood grain. I like the Ogden in ebony and walnut, but the Bubinga veneer looks like it would be very attractive. I’ve never seen the Bubinga on a harp myself, though. Hope this helps.
