SOLD: Kolstein Carcassi Double Bass


Kolstein Carcassi Model double bass built in New York by Barrie Kolstein.

Slab cut fir top, back and sides of willow, with deep ribs and unique pattern. Definitely on the larger side, instrument could be considered a 7/8ths, but set up with modern string length.

The length and depth of this instrument give it a tremendous air volume, gobs of punch and clarity which we found to be really fun to play. Often overlooked, this is a charming bass that could cope unamplified for many medium volume applications.

See video below!

Upper Bout: 20″
C Bout: 16 3/8″
Lower Bout: 25 1/4″
Length of Back: 45 3/4″
Rib Depth: 5-9″
