I’ve had a Special 22 for about six months. It’s basically a Custom 22 with a middle single coil.
The Swamp Ash pickups are a delight! I’m terrible at describing pickups, but for my low to mid-gain playing they’re wonderful. I particularly like the neck and middle together with the neck split. It’s just a great sound and unlike any others I have.
I wish I knew more about the middle pickup. It’s a Fralin, but that’s about all I know. There’s no hum or noise that I can hear from it when it’s isolated.
I’ve read in other threads that some folks had heard these guitars were weight-relieved, but I don’t think that’s the case. Mine isn’t light or heavy, but perhaps around 8lbs.
All in all, a really nice, somewhat less common guitar. All of the wonderful refinement of a later Custom 22, with an extra couple of tricks and some really nice pickups.
