Tom May

In this pic May can be seen playing his FGN semi-hollow in black.

I saw the Menzingers play in Philly in November 2019, and Tom used a Gibson The Paul for the entire show. You can tell it's a The Paul from the natural finish, the location of the toggle switch near the knobs, the dot inlays (including on the first fret), and the arm contours on the body. You can see Tom playing this guitar in multiple instagram posts as well.
