COSI Carbon Fibre Double Bass


This unique instrument was used by Shannon Birchall of the John Butler Trio. Between 2003 and 2009, this double bass was used in the John Butler Trio's standout recordings, including Aria-Award winning "Grand National". This bass has also been featured in DVDS and music videos of the band.

The instrument is hand made in France by custom brand COSI. It features carbon fibre composite front, back and sides with ebony fittings including fingerboard and tailpiece.
