Hi All,
I'm currently working on a project of renovating an old strat copy, with an HSS set up. I'm pretty much settled on a crunch lab in the bridge and from a bit of research I'm thinking of the Air Norton S for the neck pickup as it is supposedly tonally similar to the Liquifire, which is normally paired with the crunch lab but won't fit with my HSS set up. My question is, with this set up in mind what would be an appropriate middle pickup? I've read that mixing single coils with humbuckers can compromise the tone of both, and if I'm understanding correctly the Air Norton S is really a Humbucker, just in the size of a single coil pickup, have I got this correct? Does this mean I should mainly consider other single coil sized Humbuckers when looking at middle pickups, or is the change in tone from mixing H and S only marginal?

Apologies if these are obvious questions, I'm an experienced player but never got much into the tech side of things before so have never had to consider pickup combinations.

Any thoughts, opinions or help very much appreciated.
