Happy Modding II - Joystick Spring Removal

The A-174 Joystick Controller outputs 2 control voltages, generated by a spring-loaded X/Y cross potentiometer.
Two springs inside the module take care that the controlling lever returns to it's centre position if untouched.

One very easy modification is the removal of a spring from this module


The process of removing is quite simple, and is described clearly on the Doepfer DIY page / section 4.2.10.

I decided to remove one spring only, the horizontal one. ( X-axis )
This way the Controller stays fixed, even if i let go of the lever, and doesn't automaticly go back to the middle.

If you do this to the Y-axis ( vertical ) of the module, the lever would fall down to it's lowest position due to gravity, which also can be handy in some situations, but not mine at the moment.

This small modification adds just that tiny bit more flexibility to my setup.

Note: Pay attention that warranty is lost if the joystick is modified !
