Nash's previous clubs include the likes of Sunderland RCA and Billingham Town, and joined the reserves last season.
Lee Guess's comments on the signing: "Over the moon to get Nash down after an impressive stint with the Reserves at the end of last year.
He's a cracking player who works hard and has brilliant quality about him as he can score goals and create them so he has a bit of everything really.
Not only is Nash a good player but off the pitch he's a top young man and someone who will be great to have around the group."
