In very good condition, with the box
The Haymaker is a fantastic, versatile overdrive pedal from Caroline. They intentionally didn't copy any TS or Klon-style circuits to get their sound because they wanted an original sound and have achieved that.
It will push your amp into mild overdrive or high gain distortion, with a distinct British voice. It retains calrity, but still has a lot of mid-range kick to cut through the mix. And because of its 3-way mode gain stage, it has a highly dynamic range, just like a tube amp.
So it responds when you pick softly or when you give it a bit more attack.
