Mine is " so you built these amps transitors, qualities, from scratch, why does it have to include a "fake ribbon mic, or fake "57" in the model. But the answer is becuase its the only way to capture the qualities of the cab that generally goes with that amp, and that its not a "fake" mic, becuase its hopefully what was used to capture it.
I think someone above explained you CAN remove the "mic" variable from inside the modeler, perhaps I will do that.
I am not someone who needs convincing or anything I am just wondering "why" people say these things about modelers/amps but again its semantics. Whats not semantics is that it truy does include a "mic" sound with "placement" in all sounds. Even if youre trying to be dead basic as pluggin into an amp in real life.
I can see why someone would draw that conclusion - "hey if you can simulate a tube and I can change a bunch of things there,,, surely you must be simulating a speaker, the box and the a mic as well - why can't I remove the mic in this model?" But that's not exactly how speaker cabinets are simulated.
Note that to date - there's no system so far (even non-realtime) that can model a guitar/speaker cabinet box virtually, from specifications of the components themselves - maybe this is where the confusion comes from?
Cabinet simulation is done by doing convolution of your signal with a captured impulse responses of an actual guitar cabinet, which requires a microphone to capture.
An IR maker/producer/vendor could decide to use a calibrated measurement mic (For example TC30 -
http://recordinghacks.com/microphones/Earthworks/TC30) to capture and remove the contribution of the mic to the final impulse response - note there's no tools in the box for you to do this - you either have to capture it yourself or find some IR vendor that provides those choices.
However, the approach taken by most vendors and Fractal Audio now is to capture a speaker cabinet with typical microphones used on a typical guitar recording session - In the case of the built-in IRs, that mostly SM57/Royer R-121 and a few others. IR vendors have a plethora of other choices as well.
The key here however, is that the response of the microphone and the cabinet are combined in the impulse response - you can't separate it.
There are I think maybe about 4 IRs, that were captured with the TC30 in the built-in IR list - but that's about it.
Hopefully this explains it.
