I was talking to Ollie on a different topic and asked him about these, and he said he is now putting these in all his new pedals. You can also order one of these for replacing a scratchy pot. Before talking with Ollie, it just so happens I had ordered one of these thru another Goodrich dealer that was selling the pot. So far it is working with not the slightest bit of static, looks very promising!!! Ollie told me the way to be certain you have the new and improved pot, is to find the letters "HL" (indicating High Life) stamped at the end of the part number on the back of the pot. Here is the write up about the new pot:
This is the Goodrich 500K direct replacement pot for the 120, L120, H10K and L10K Series Volume Pedals. After painstaking research and development all Goodrich Volume pedals are now coming equipped with the new ULTRA HIGH LIFE 500K audio taper potentiometer. The High Life Pot is capable of one million cycles, which is almost 10 times the life of the original 500K volume pot. The Goodrich Ultra High Life 500K Potentiometer is suitable for use in any volume pedal that requires the use of a 500K audio taper pot.
