Preparing for a little holiday rewiring, I got myself a pair of no-load tone pots, proper Fender-branded ones with the detent. They go to about 270k, then disconnect at the detent at 10.
And I see that as a mistake in the design. The whole point of having a detent is to give a tactile reference to a particular position on the turn of the knob. In this case, it should have been the point where resistance is maximum, but before it disconnects, ie, at about 9.
But the detent is right at the end at 10. There’s no point in having a detent at 10. If I’m hitting the end stop I don’t need a detent there as well. So it achieves nothing except to make it a bit more awkward to control the high range. Tweaking a new American Standard in a shop, I saw that it also had this type of pot with the same error. I’d rather use a home-made no-load with no detent.
I was also speculatively hoping that once the wiper arrives at 10, it would connect to the third lug – and i had some ideas for that. That was my risk, its not part of the design intent for these pots. However, it does not occur.
I’ll probably recycle these pots on ebay.
cheers John

John, The actual intent of that detent is to prevent accidental re-engagement of the Tone circuit. IOW, if the knob were to be unintentionally brushed by a passing hand, it won't easily move back the tiny bit from 10 that would reconnect the Tone circuitry. Simple, if a bit off-putting to some modders. HTH sumgai

I think i had made such a non-load tone pot myself by scratching away the conductive material at around position 10. Didn't notice any difference in sound, besides that "bzzz" when dialing the pot on and off at the end of the pot circular journey.
