A description of the axe reads: "Envisioned and designed by St. Vincent with support from the award-winning engineering team at Ernie Ball Music Man, the unique electric guitar was crafted to perfectly fit her form, playing technique and personal style."

You can check out the specs and details, and more pics, on the Ernie Ball website.

It's actually the same guitar she played when covering Beck's "Dreams" with Beck himself and Taylor Swift.
