Info on this is quite sparse and over at least 3 different forums. Replacing the crap lever on the back with a rotary linear pot. What pot did you use. I see 5k ohm mentioned a lot but also a 1k ohm with resistors. How many turns is your pot? 1 turn? less than 1?, 3? Do you use the full range? Any problems? I saw in one thread where someones controller stopped working after using a 5k ohm pot. I know the stock pot is 5k ohm but it only uses a small section of it. Where have you positioned the knob? Long term successful users most welcome. Many thanks for any info.
