hard time to bias flangers and phasor 2

[pietro_moog]

hi guys. i built a current lover, 2 collosalus and a phasor 2.  the sound good but very far away from the demos
of you guys. basically i'm having such an hard time to bias them right.
do you have any suggestions? i am very down at the moment. i can't find the sweet spots that make them sound fantastic. so sad.
