Hey,
I recently bought a Verbos Complex Oscillator and it is absolutely the most amazing module. It's got incredibly huge warm sound that can go full brashy to soft and warm balloons. And yes, it can go way dark and big (play those minor triads!). I'm loving the Trident also but at nearly $900 right now, that's a huge bite, when I can create similar tone from other modules in my racks.
Others have already said it here and it bears repeating: you can create a complex oscillator out of your existing modules if you use another VCO as a modulation source. Pick something large and warm as your "base" VCO and modulate with just about any other module. Experiment and see what you come up with. I often pair a Castor & Pollux with either Plaits or one of my warm Doepfer VCOs.
Before I bought the Verbos, I used four Electrosmith 3340s detuned slightly to create monstrously huge dark drones. Controlled with a Befaco Muxlicer and a clock set to way way slow. Dark times, my friend. Dark times.
Have fun!
