Seimitsu LS-56 Joystick (Panasonic switch)

A popular joystick, coveted by "shmup" fans due to the heavier spring and medium engagement distance.

The LS-56, paired with a Seimitsu octagonal gate, is considered to be the most formidable "shmup" joystick currently available today.  

Sold with the default square gate and Seimitsu MS mount plate, however is compatible with the Seimitsu P-40 mounting plates, sold seperately.
