This model is the black bat top/Japanese mounting/Korean microswitch, version of the Crown 307.
The 307 is Crown's answer to people looking for a grommet style stick that plays like a JLF. This amazing new stick has combined Crown's traditional grommet centering system with newly designed actuators and a variety of microswitches to create a smooth and sensitive feeling stick for the fighting community.
Crown sticks come with one of two microswitches. the KMS models are Korean or Gersung microswitches, while JMS models are Panasonic based style microswitches. Both of these styles come with the .187" tabs used in traditional joysticks that can easily be adapted to a fight stick with a conversion harness.
The designation "J" in the 307FJ indicates that this is a japanese style mounting plate with the appropriate holes compatible with most Sanwa JLF mounts. This is different than the "K" in 307FK that indicates a Korean Style mount.
SILICONE VS. LATEX GROMMETS
Silicone was designed to increase the durometer (stiffeness) and provide a more elastic feel to the stick. Silicone creates a feel that is closer to a spring with mild dampening than the more heavily dampened system of latex. For users of Japanese levers, the silicone will feel closer to the spring returns they are used to with more consistent resistance throughout the range of movement.
Of course, just use one of our Crown hollow shafts. 6mm hollow shafts allow for almost all Japanese style balltops, while 10mm allows for the Paradise custom RGB ball tops.
