Investors previously told BBC Scotland News that they lost up to £12,000 after the company was sold.
Some of them said they were doubtful of regaining their losses through Second Best.
Gareth Fitzgerald, who spent £1,000 on Brewdog shares, said he would sign up for the new scheme.
But he was doubtful over whether it would pay off.
“I’d be foolhardy not to, but I’ve got to say I’ll be a very, very passive investor,” he said.
“I won’t be buying any of his products, but it would be silly not to sign up.
“19.3% sounds good – but 19.3% of nothing is nothing.”
This sentiment was shared by fellow Equity for Punks investor Pete Berryman, who invested around £3,000 on behalf of him and his sons.
“It’s a nice idea that potentially we’re not going away with nothing, I’m just wondering what strings are attached,” he said.
He said would follow up on the proposal despite being “very cynical” and said he “will be checking the small print”.
