Gary Bowyer hailed the players and the supporters after they despatched Stoke City 4-1 to progress in the FA Cup.
Josh King scored a first hat-trick for the club as Rovers got the better of former boss Mark Hughes' side at Ewood Park.
Peter Crouch put the visitors in front before King and Rudy Gestede took centre stage with an emphatic display of forward play to which Stoke had no answer.
King levelled for Rovers with a close-range header before Gestede scored from the spot just before the break after Geoff Cameron saw red for bringing down King.
The second half belonged to the home side and King in particular who twice raced clear of the Potters defence to put the game beyond Stoke and Rovers into the last eight of the competition.
"The lads are buzzing, they are delighted and rightly so," Bowyer told Radio Rovers.
"For myself and the players I think it is probably our biggest achievement in the time that we have been in charge.
"Full praise to them and full credit to them, they deserve every plaudit going.
"To go behind in the manner that we did was disappointing but the response and resilience to bounce back was tremendous.
"It was a major boost to go in front just before half-time, then the timing of the third was crucial. To get it so quickly and then to back it up with the fourth was just incredible for the lads.
"Against a quality team the lads worked ever so hard. It is a great example for them in what you can achieve when you do that.
"It was a real cup-tie, the players and fans made it like that."
