So, it is expensive for what it does, but it was precisely what I needed. 2 of my ESP guitars had this mini split switch that were unused and this EMG kill switch fits the routing perfectly. Since both guitars are equipped with EMG solderless stuff, this should have been the simplest and fastest parts swap in history.
But because it was too simple, the instructions were wrong and it took me 1 hour instead of 10 minutes to figure what the problem was. Following the instructions, the pickups would sound weak, with no sustain at all, but swapping things around made this work as it should.
In the end, I am very happy with the purchase, but it could have been perfect experience.
