The short answer is that it isn't just that they make you louder. They do make you a bit louder, but loudness is a psychoacoustic phenomenon. There is more to it than just that. In the Saturday session I mentioned the principle of acoustic masking. That's a big piece of it.

This is a beautiful arrangement!
Our next Pop Up Class is this Wednesday and we will talk about the Diminished Scale.
This ties in with our last class which was on "Have You Met Miss Jones". All the dominant chords in this tune are 13 b9 chords. That's the diminished scale. So we will talk about this this week and then the following week we will do an online performance where we will each try our hand at "Miss Jones"!
If you want to attend the class make sure you are a paying subscriber and email me me your user name and your email address (Which of course is in the email heading!)
The tool I used for this (Insight) is part of Izotope's mastering suite of software. This is not its normal use, but it provides a nice visualization of acoustic energy in real time across the frequency spectrum. Something went awry with the way that Quicktime did the screen capture, so by the end of the video, the waveforms are appearing significantly later and out of sync with the sound, but you will be able to still associate them and see the differing harmonic content. The frequency is represented along the bottom of the graph.
I am always asked how good or bad my € 100 DIY-pickup-system is.

This question is difficult to answer, since a lot has to do with personal listening impression and personal preferences. I now had the opportunity to record my playing simultaneously with two computers. The recordings were made with the freeware audacity on the computer.
The only change I made to the recorded signals is that I normalized all levels equally to -5 dB to make the sound pressure comparable.
