At 30 x 47 ft., Studio "B" was the largest studio in the KOMO building (there was no Studio "A"). In addition to the control booth and sponsor's viewing booths (center), there was a special music director's booth at the far left. The room was decorated in soft grey and blue.
The theatre pipe organ at the far right was brought from the previous studios in the Skinner Building. The pipes are located behind the grill at the top right.
