Hi Till, great line of pedal you have. Very nice graphics! I see Musikding pedals, so I guess you are European or German?
What is your experience with the Musikding Noise Gate?
A Wire pot i think. There is a unisolated wire very evenly wound around a high ring and the wiper turns 300 degr. around on the inside touching the wire. Built this way it should be linear.
They have their on facility in Paducah, KY. This was also the home of the CTS company and other manufacturers. Read here:

I recently socketed a BSIAB which calls for 3 stages with those jfets. My experience was that the 2n5457 and thd j201 had a slight difference in gain, but the mpf102 was remarkably lower that the other two. I settled with the 2n5457 being in the middle.
