The Kay Junior with its 35-1/4” string length and smaller dimensions falls somewhere between a 1/4 and a 1/2 size bass. This one from 1966 is in excellent (near mint)  condition and has been set up with a new adjustable custom made bridge and fingerboard adjustments to play easily with a full sound. Strings are Pirastro Flexicore D and G and Helicore Orchestral E and A. Includes cover. Generally a fun size for an adult and small enough for a child bassist.
