Sanwa Denshi's JLF/JLX/JLX2 series joystick has been the joystick of choice among the majority of arcade stick users for the past few decades and has continued to perform even better the past few years

Otto DIY specializes in upgrading individual parts of the joystick to increase performance by minimizing friction (with the use of Teflon), therefore providing smoother motions and more accurate output

Up to this point, we've only offered the Otto DIY products as a kit, which you would mod yourself.  We understand there are some users out there that are too busy or simply do not want to modify this, therefore, for the first time, we're offering pre-modded Sanwa Denshi + Otto DIY modded joysticks

Choose Your Style

• Otto V1 - Anomalous Roller (Pivot) - If you prefer a very short throw, here you go.  You can invert the pivot to achieve two types of feedback.  With the pivot tapered downward, expect a faster return to center.  With the pivot tapered upwards, expect a "bouncier" feedback and a shorter throw
• Otto V2 - This simulates the feel of a Korean Lever
• Otto V5 - Improved components to the Sanwa Denshi JLF stock parts.  Basically it will still give you the feel of a Japanese JLF lever, but with smoother more accurate motions
• Otto V5 with Steel Core - In addition to the Otto V5 mod you see, we added the Otto V5 steel core to provide buttery smooth inputs.  Additional upgrades are just cosmetic, EX Gear aluminum shaft and custom Otto V5 printed mounting plate.    
• Added 10/04/2026:  Otto V5M+ with Steel Core - The M Series V5 core functionality uses the core components of the classic V5 module.  The parts here are refined to improve the input accuracy by using short hinge switches (Omron D3V-161-3A5 - which can be easily swapped with similar switches to change the actuation force).  The steel core is added to this mod to provide buttery smooth motions.  Note that these switches use the .187 connectors so make sure to add in a .187 to pin harness if you don't have one already.  

What's Included?
