Hi, it is in fact a Happ base but it has my shaft and knob. The knob that Happ sells is a smaller knob, I have introduced a 1/16th inch larger knob (same size as the original with a matt finish)and a shaft that is 3/4 of an inch longer to accomodate wood control panels(something most of us are using to build our panels) and 2 eclip positions so you can use it on a metal panel. The sticks are also available in colors, something else Happ doesnt do, Yellow, Blue, Red and Green.
While it is true that is doesnt feel like the original, nothing will because leafs and micros are 2 different animals and noone makes a leaf anymore to my knowledge. It does have the diamond pattern on the bottom similar to the original so it absolutly positivly 100% without a doubt will not do anything but 4 ways. FI you are having trouble with your stick, look for a bent or out of position actuator arm on one of the switches, that or a bad switch is the only thing that can cause it to have a dead zone mechanicly speaking. If in mame, i suggest checking all your settings as you could be experiencing some delay in your computer. Tornado Terry
