ok people! shake hands and forgive earch other 
thanks for the answers! i listened to some pedal review, and i think that this sound, the "sub-flange a-la Geezer" sound cound be reached with an MXR 117 or a EHX Deluxe electric Mistress.
The thing is that those pedals are really TOO expensive here in Argentina... the Boss flange it's good but i didn't hear a demo with the deepness of the sound i'm looking for...
