So I picked up a Sidewinder umax

Just read your post about adjusting GB.
From what I read, if GB'ing at min disc setting and moving the disc up, GB goes negative and I would have to adjust GB to be more positive. And if I reduce the disc, I have to adjust back negative.

Now I do plan on bringing the threshold and GB control to the faceplate so they can be adjusted externally. I will also have a fixed factory GB setting as a reference point.

On an older Silver Sabre umax---
I have found that replacing the GB trimpot (100K) with an external 3 3/4 turn (100K) multi-turn pot was no better than a single turn. The adjustment range was very small. What I did to increase the usable range was add a resistor to the external control pot to change it into a 50K. It made a big difference.

I will see if changing the value of the original Sidewinder trimpot similar to the Silver Sabre has a similar effect
