I went down a whole Sheehan rabbit hole years ago. Attitude bass, Signature drive pedal and 2 channels. I learnt a hell of a lot about sound design for bass doing that. I also realised I didn't need a 2 channel setup like that for a cover band, so these days I'm more restrained.
I still have a semblance of dual channel processing within my main helix presets, but that's for clean and wet, rather than gritty highs and lows. But I'm more conscious of my mid-range and frequency slotting since going through this Sheehan phase.
Actually. One of the reasons I bougth the Helix was so I could create a better 2 channel Attitude bass patch with Billy's Pearce preamp model, and instantly switch to a traditional single band signal chain. Funnily, I've never gotten around to it in the 5 or 6 years that I've owned it.
