Keep in mind that the guitar lead is being recorded DIRECT from my Kemper. There are no mics involved. I'm monitoring the recording session and playback through the same exact setup.
Ah but there IS a mic involved. Speaker cabinets too.
You're listening to the sound recorded by your security system. How did the security system record that sound? With a mic, correct? And how was the sound being produced in order for that mic to pick the sound up? It was playing through your reference monitors, correct?
If so, then there you go. It is almost inevitable that the audio you hear from your security system will sound different than it will when it comes right from the computer to your reference monitors. The fact that is sounds better on the security system makes the situation worth looking into.
So now you must determine what the combination of reference monitors and security mic as well as security mic placement might be doing to the audio. Is the security system mic in a corner of the room? A corner where standing low frequency waves might live? Standing low frequency waves that might make a guitar sound fuller perhaps?
Sounds like its time for experiments to me.
