You can play monkeyball with the regular analogue stick casually and it works but keep in mind for the later levels you don't have the precise control of the jlk gf2 at stick/amp used on the original cab.
Just wired the stick up using the harness you made. Right off the hop they worked no calibration needed. I also don’t know how to calibrate them lol. Thanks @notsonic for the write up.
