For Thunder guitars and basses with controls for volume, passive tone and active tone
We presume from the reference to models now having pull switches for coil tap and phase that this dates from 1985/6.
Although the manual only refers to the Thunder IA and IIA lead guitars and Thunder IA and III basses, the controls are the same on the early active Thunder II basses
