Chris Hadfield's Space Oddity has a nice fuzz bass tone.

I'm working on a cover from the original System Shock 1 video game, specifically the reactor level theme that I would like to cover with rock instrumentation.

I would like to have a bass tone similar to the one they used in the video above.

I have a fuzz pedal (Nine of Swords Twin Earth) that works well with bass in general, but I'm a complete bass noob and so far I haven't been able to approach the smooth, linear and predictable gruff of the video. The bass is a Squier vintage modified p-bass 5 string with passive pickups.

To be clear, I'm not looking to exactly replicate this tone, but I'd like to get the nice regularity and sustain in the distortion.

I have tried many settings of gain, tone knobs, volume knobs and many other things on every piece of gear that I have and I'm starting to wonder if I'm not confusing a fuzz bass sound with a run-of-the-mill distortion.

So far I've had some moments I felt like I was breaking through and I managed some decent tones, but nothing that sounded as linear and crisp as the video. Always either too sputtery and unpredictable or not enough gruff in it.

Apart from "sell your house and buy a vintage big muff", is there something super basic I'm completely missing here as far as fuzz bass goes?
