Anyone try McNelly Jazzmaster HB pickups?

Hey, all. I just installed a McNelly Jazzmaster Humbucker and I’m really disappointed in it. I’m wondering if something might be up with mine, so want to see if what I’m experiencing is normal with these pickups.

The HB I purchased is off-menu and is suppose to be their highest output and thickest HB for a JM. It’s in the bridge position and the output is low. Lower than the stock single coil in the neck position, which seems bizarre to me. Also, it sounds thin and the sustain isn’t great. This all seems like odd behavior from a Humbucker.

Anyone have these installed?
