So, I wanted a single guitar that would cover most of what I would want individually from a T and an S guitar. The result was this thinline with an ash body and maple neck and T-style bridge and pickup with S-style neck and middle pickups. The switching is a bit goofy with the 3-way toggle allowing the selection of T, S, or both and the slide switch giving neck, middle, or both into the toggle switch. With this set-up I am able to get all six possible pickup combinations. Obviously the bridge sounds very much like a T, and the neck/middle selections sound very S, but I was pretty pleasantly surprised that bridge/neck sounds very similar to a T middle position while bridge/middle at least to my ear captures the Lay Down Sally/Sultans of Swing/Sweet Home Alabama sound remarkably well.
As someone who has spent countless hours/days/weeks of his life looking for that tool "I was just using," it's amazing how much better I've been about putting things away because they all have a defined place and they're still easily at hand. Here's a look at the whole thing...
Don't know how I missed your original post way back when - that's truly a beautiful design.
... and a tip o' my hat to your Yankee Screwdrivers. Owning one was a lifelong goal for me starting at about age 5.
