I've used bass amp modellers for years.
Mostly Line 6 stuff, but also Tech 21
I'm using a Helix now and the bass models in it are all very different.
There's SVT normal channel, SVT Bright, Mesa 400+, a GK model, B15 model and other stuff too. And the best bit about modern modellers with powerful EQ is that all amp models (even the guitar ones) can be used properly on bass. In parallel signal paths if I fancy it too.
