Tips on making Dark drones?

this is my rack im building atm

i dont have the tetrapad-tete s yet,and the veils seems to be broke.

anyone have any starter tips to patch up dark drones/ambient drones

Any sound examples from other artists that represent what you mean by "dark drones"? Maybe we can help you reverse engineer a similar sound to what you are aiming for.
Edit* I think I know what you are going for, and the E352 will probably be a great tool, but it would help to hear some examples.
