The Core Conservatory bass is an advancing-level bass. Fully carved spruce top, maple back and sides, wood aged 3 years. Exotic dapple finish adds to the unique character of this instrument. Includes endpin and maple bridge with height-adjusting wheels. Adjusted with D'Addario Helicore strings. 3/4, and 1/2 sizes. The Core Conservatory bass helps musicians take their playing to the next level. Practicing, lessons, and rehearsals require a student's commitment, and these instruments reward the extra efforts with greater range of tone and dynamics. The luthiers spend more time in carving and shaping the plates for improved acoustic response. These and other subtle details signify better overall workmanship which make a big difference and help the players' musical education flourish.
