Joystick model LS-38-SC-K offers two firsts in the Seimitsu family: a noticeably higher tension spring, and a cover for the LS-32 style shaft.
Higher Tension Spring
Originally started as an experiement to improve response and return to neutral, Seimitsu had a rather daunting challenge in affecting it's most popular joystick in the market - the Seimitsu LS-32-01 Joystick. The spring's original diameter of .8mm was increased to 1.0mm, offering a denser spring overall. This is similar to the 2lb Tension Spring for Sanwa JLF, though subjective feel is 2.5lb. Overall, those who desire a stiffer equivalent to the LS-32 will find the LS-38 a favorable alternative.
The LS-32 has long come without a shaft cover. The LS-38-SC-K remedies this by adding a larger diameter black cover specific to the LS-32's unique shaft. Please note that dustwashers and shafts from the LS-40 or LS-56/58 series are not compatible with the LS-32 or LS-38.
SE/RE Mounting Plate, Balltop
Seimitsu's "SE" (originally called the "RE") flat mounting plate is compatible with the Seimitsu LS-32/LS-32-01 and LS-40/LS-40-01 series joysticks. This plate mounts directly under the control panel, unlike the Seimitsu SS Mounting Plate for LS-32, LS-40, which is is compatible for installation within a MadCatz TE or similar fightsticks. The SE mounting plate is best used for arcade "candy" cabinets. This mounting plate can be swapped with the Seimitsu SS Mounting Plate for LS-32, LS-40.
Compatible with a wide array of Sanwa and Seimitsu balltops and battops, the Seimitsu LS-38 series joystick comes with an adjustable restrictor plate for 2, 4, or 8-way operation.
Bundle Control Accessories
The LS-32 Round Main Guide enables LS-32 and LS-38 joystick fans the same smooth 360-degree control as Sanwa JLF owners enjoy with the JLF GT-O Circle Restrictor Plate Insert. This main guide replaced the light blue square guide on the Seimitsu LS-32 and LS-32-01 joysticks, and fits below the dark blue subguide.
The LS-32 Round Main Guide provides works with the default subguide, but for near perfect 360 degree control, you can add the Seimitsu LS-32 Triple Restrictor Plate. This allows the actuator to easily hit the switches, affording the best control you can get with the round main-guide.
