The 21-year-old winger, who came through the Bee's academy and made his first team debut in April 2012, has scored three goals in 17 appearances this season.
And Gambin says the Bees are buzzing as they prepare to travel to the Kingfield Stadium.
"It is a great squad and we have got a great group with great leaders and great players," he told the club's website.
"It is enjoyable to be around and train with the players at this club every day. We are all enjoying what we are doing and we are all working together to achieve our aims.
“It is a wonderful experience at the moment. I love training every day and being around the boys. We have got a great bunch of lads and everyone gets on with everybody else.
“It is a real family vibe and everyone is looking out for each other so it is all going well and hopefully we can make sure that it stays that way.”
Barnet are eight points clear at the top of the league, 10 points ahead of Woking who sit third in the division.
Gambin added: “Morale is very high and everybody is pulling in the same direction so it has been good.”
Barnet boss Martin Allen has no fresh injury concerns ahead of tomorrow's match.
