I started using exlusively Obsidianwire harnesses since 2020 (two traditional strat harnesses, one with Blender, and two HSS).
I bought this to replace one of my old HSS harnesses, I was only interested in the HSH mode (there is a HSS/HSH on the PCB) switch but I also wanted to have the extra pup combinations available so I opted for the 7 way switch.
Qualitywise, Obsidianwire is top notch. End of story.
This one can also do (via the Push/Pull on Tone 2) Bridge+Neck and Bridge+Middle+Neck.
If you are not like me, always operating my pups on full humbucker mode, this harness can autosplit (just use all four cables of your humbuckers instead of two).
My strats are Fender Japan (CIJ and MIJ) and these harnesses fit just fine. The same goes for the MIA strats.
So, if you are sick and tired about soldering, just find the proper Obsidianwire that meets your requirement, install it, and forget all about it. Works great for guys and gals that are experimentng with different pickups all the time.
