I got 2 of these for 2 guitars I’m modifying.
I’m using both as volume pots. In both cases, the taper is really weird, resulting in low volumes for the first 80% of the travel, and all the usable difference in the last 20%.
As the other reviews have commented, you don’t get a “clean” detent when you get to 100%, it’s more spongy or springy.
The kill switch itself is a bit tricky. Surprisingly, the mechanical button doesn’t consistently work. In the tele style guitar, it didn’t work til I fully reassembled it. And I think I’ll need to set it up again, with the pot sticking slightly further out than I’d ideally like.
I haven’t wired the kill switch on the second pot yet, I hope it works well. I intend to use it to remotely trigger an inbuilt. Effect.
