Phaser in gen~

I am trying to implement this phaser algorithm from the book "Audio Processes" by David Creasey in gen~ but I don't get any crucial audible difference. I think the problem has to do with the second order all pass filter but I couldn't figure it out. I would appreciate any help, thanks in advance!
