I've installed the switch and so far I like it. I wired it to be a standard 3 way switch for the two pickups in one row (positions 4 to 6) and in the other row (positions 1 to 3) it switches between a pre-set of full p with a bit of j and a setting the other way around. Both settings in a perfect sweet spot of blending, loading and phase cancellation. The middle position is a 100% blend of both pickups so position 2 and 5 are the same.
I mounted the trimpots for the extra settings on the back of the switch. In hindsight I could have gone for smaller value pots. These are 100k, 50 k would have been enough.
The extra switch is where the old on/off switch for the pre I had in there for the last 10 years. As my amps and cabs have improved over the years, I found out I started to prefer passive.
Because I had the space left, I turned it into a series/parallel switch for the P pickup. Not sure if it will get some use, but it covers the hole.
first impression is its ver fast and easy to use. I'm eager to find out if my assumption is right and this will cover all my switchin needs.
