Seeing how popular the Noble DI/Preamp is with bass players lately it’d make a nice addition to the handful of bass amp models that are currently on the Quad Cortex. Line 6 has a model of it in their stuff that’s supposed to be pretty close to the real thing (although I’ve never played through a real Noble myself) so if they can figure it out then it shouldn’t be too hard for Neural.
It might be nice to have some other kinds of preamps that are commonly used as well. I’ve used an Avalon U5 and a Branch Audio Tree II in a studio setting a couple times and really enjoyed how my bass sounded through those units as well. I could definitely see people having a use for those in their signal chain, especially since some pre amps like the Tree II are used on vocals sometimes as well
