Solderless setup with all required wiring available here.
A pickup set with one aim in mind: alleviate the typical P90 set issue of a mismatched flabby neck and a thin bridge.
P90 necks can sound beautiful when wound to a nice clean vintage spec, but they're usually mixed with similarly wound bridges, making them too thick relative to the bridge. Switching between the two pickups results in a severe EQ imbalance that makes it near impossible to find a good amp and pedal setting that will work for both. The best you can do is find a middle ground - which leads to a compromise in both pickup's tone.
This set was built around a clean and clear neck pickup. The goal was to create a bridge that would match well with it, with a fuller than traditional tone. But it had to retain clarity, like the neck. The neck was wound modestly to retain the quintessentially beautiful vintage P90 neck tone.
The bridge is fatter as a result of a special winding pattern and over-winding. Easing up on the volume will make it become a beautifully articulate piece. The aim was to fatten up a standard P90 bridge without making it ...murky.... and the Murky Horizon bridge is the fruit of that labour.
