I did send a ticket and was told that new Amps in Bias FX2 cannot be edited in Bias Amp 2. The Celestion IRs are embedded/integrated into Bias Amp 2's software. It seems that the Bias Amp 2 is a bit redundant and only works with the stock amps included in the desktop app. However the clean amps sound great, the high gain is what sounds just awful. Finally got my focusrite today and bias amps 2 sounds like tinny garbage, like if you were to buy one of those really cheap pedal modelers or really cheap combo amp. BIAS AMP 2 gives you the power to create new sounds by designing your own dream amplifier, letting you swap out tubes, customize preamps, power amps, transformers, tone stacks, multi-mic capability and open/closed back cabinet, all via a powerful and intuitive photo-realistic interface. The flagship BIAS Amp 2 Standard plug-in ups the ante on dynamic tube amp behavior and features new tube types with more headroom and low- and mid. This blending/morphing of mic distance IRs as you move the mic graphic, I would assume offers more 'in between' sounds too because the IRs are fading in-and-out of each other behind the scenes in the internal software.or 'overlapping' for a better word. Bias fx and bias amp 2 sounds like trash. BIAS Amp 2 Standard is fully customizable, letting you create amp models by swapping out the tubes, preamp, transformer, tone stacks, cabinets, and mics to create your own signature amps and sound. This is what I refer to as 'morphing' in my statements above. BIAS AMP 2 revolutionizes virtual amp design, providing the tools to take your finished guitar tone anywhere from studio to stage and back again. You can use Amp Match to clone the tone of real hardware or a guitar track, or connect to the ToneCloud to gain access to thousands of custom amps from. In my opinion, it's better in BA2 because when changing through the mic distance IRs, the change in sound is gradual and smooth.not abrupt like changing IRs in third party loaders. BIAS AMP 2 is the ultimate virtual amp designer, authentically recreating the tone and feel of real tube amplifiers, while allowing you to mix and match components to create your ideal amp. You can of course use your previous Celestion IRs, but it will be far more tedious in comparison and you will need a loader that can load and blend two mics at once to get close to the sound options BA2 now offers. You can also use 'dual' mics now so that makes even more sound options available. It now does all the loading/blending work for you and this is why it's more than just 'Bias amp 1' with Celestion IRs in a folder somewhere.they are literally part of the software's inner workings. Where you would 'normally' pick individual mic/distance IR files within downloaded celestion IR folders, those individual files are now selected in BA2 by choosing the mic from the menu and moving its distance with your mouse around the visual diagram which in turn blends/morphs through all those files you would normally have to select and try individually.
