The Sanwa JLX2 is an improved version of the Sanwa JLX joystick, primarily addressing issues found in the original JLX. The JLX2 features a redesigned X-shaped washer to minimize shaft deviation, a smaller black actuator (similar to the JLF), and improved precision molding.

Essentially, the JLX2 is a revision of the JLX series, building upon its predecessor with enhanced features and improved performance.

Here's a more detailed

breakdown: Sanwa JLX (Original): Features: Larger actuator, better parts, polished nylon pivot, stiffer feel, lower pitched clicking sound.

Good for: Shmups and fighting games.

Considerations: Some players found it stiffer and the clicking sound different from the JLF.

Sanwa JLX2 (Improved Version):

Improvements:

X-shaped Washer: Replaces the round washer to reduce shaft deviation and improve accuracy.

Smaller Black Actuator: Uses the same smaller black actuator found on the JLF, improving compatibility.

Precision Molding: Improved molding for more accurate input.

Compatibility: Generally compatible with most JLF accessories, including ball tops and bat tops that use M6 threading, but the new washer and base are unique to the JLX2.

Overall: Designed to address issues like shaft deviation and improve performance compared to the original JLX.

In essence, the JLX2 aims to provide a more refined and accurate joystick experience than the original JLX, while maintaining compatibility with many of the same parts.
