SALE PENDING: Kai Arvi Double Bass, 2018, P.E.I., Canada


2018 Kai Arvi double bass looking for its first owner.

Super clean instrument with signature Arvi pattern, Kai’s consistently high-quality build and broad tonal palette.


Kai Arvi, 2018, Prince Edward Island, Canada #154

Super clean Kai Arvi double bass has never been owned, some setup work from Dennis Roy of the Boston Symphony. Dennis says, “These instruments possess a professional quality playability as well as a wide variety of tone colors at your disposal.”

Essentially a new Arvi, shop-seasoned and comfortable with itself but barely played. Features his elegant slope-shouldered pattern, this one on the slightly smaller side. Nice broad planed flamed maple neck. Maple back and sides, little to no flame on back, just a couple broad curls to it, with slightly more figure to the ribs. Venetian Sloane Tuners. Nice setup, ready to go.
