The Arona basses have bodies made of either swamp ash or alder depending on the final finish and a three-piece, bolt-on maple neck. The neck is shaped with the famed Sandberg "C" shape and adorned with a rosewood fingerboard.

All hardware is chrome plated, including the Sandberg designed bridge. Cort is the first manufacturer to use the Delano Desonic pickup system that's found on very expensive, custom-built European basses. The Desonic pickups use two bar magnet pickups with 9.5-mm pole slugs and custom coils. The pickups drive active electronics that have a push/pull volume control and separate balance, treble and bass controls.
