The fact that they have brought on board Neural Amp Modeller is very interesting! I've been using the Open Source application for quite some time, from release I suppose. It's profiling abilities are really rather good and "Steve Ack", the chap behind the application could have charged for it over and over it is that good, but chose to keep to a "free for all" license.
A user led repository already has a huge amount of bass gear captures (usual guidelines apply regarding the caprturing process) https://www.tone3000.com/search?search=bass&q=bass .
Quad Cortex's user uploads are pretty huge too, so having the option of either is nothing but a good thing - though I wonder if there will be cross-compatibility between Neural DSP and Darkglass. In a funny sort of way, they kinda compete, but then, don't?
