"He's got a lot to offer, not just on the pitch, but with some of the experiences he's had in life. He can guide one or two."
The Steelmen have also re-signed midfielder Sam Ives. and added ex-Notts County defender Nathan Fox.
Ives, 21, is a former Cambridge United trainee and joined the Steelmen last summer, while 19-year-old Fox came through the ranks at the Magpies.
"Sam is a very technical footballer and I want people who can handle the ball in the squad. He's been training with us and stood out really well," the Town boss said
"Nathan made his debut in the Football League with Notts County at 16 and was rated very highly. It didn't quite work out for him, he lost his way a little bit and we can give him that platform to express himself."
Meanwhile, Steelmen centre-half Phil Gulliver, who had agreed non-contract terms for next season, has chosen to join King's Lynn Town instead.
"Ideally, I would like an experienced player at centre-back but you can't always pick and choose," Sampson said. "I was disappointed to lose Phil but in the non-league game, these things happen."
