The preamp that is present in all Midland LMR microphones from at least the Syntech I era through the XTR to Syntech II era was included in the microphone from the design to production to distribution to provide maximum intelligibility; not increasing button count. It is transparent to the user. Ask anyone who has tried to use a non pre-amplified microphone on one of the Midlands what their success rate is.
There is slight noticable difference between AM and FM radios and how they treat the information sent from the microphone. In FM, the audio shifts the frequency. In AM, it provides information on the carrier. It is much more likely that the AM operator may see the need for audio "tailoring" via the microphone, and it is highly likely that there would be some device to interface the operator's appendages to the tailoring circuitry. In plainer english, there are "knobs and buttons" in in most applications tha require himan intervention to make them work as designed. It might be a toss-up as to where the most amplified D-104 microphones are used; on 11m or HF in general. For the most part, those who ridicule past CB operators the most, do so to QRM the memory of themselves having operated there in the past. This is kinda like the reformed smoker. He did it for 40 years, now has quit for 2 months and can't stand to be around anyone who has walked through second hand smoke in the last week. Here is another rhetorical question: Why do we, as Hams, have to excell in the art of ridicule for others? Wouldn't it be time better spent in trying to improve out operating procedures/habits; rather than marginalizing those of others that may remind us of ourselves years ago? (Now, lets see who screams loudest about never been on 11M at anytime in their life. Some will be able to recall time spent in the womb to empathsize their denial).
