Had my OM three years now. The LR Baggs Elementis pickup system really picks up the fundamental tone, and I have software plugged into LogicStudio that can separate the strings, and it doesn't manage it with any of my other guitars.

I have mentioned before on other threads that I was first curious about them as in a distant past I used to design vibratory structures such as feeders, screens and vibrating tables for industry. I used to adapt the double X design from guitars for vibrating tables to give an even distribution with little dead or live spots.

So, when Rainsong reckoned that by removing the bracing you remove the damping at arbitrary frequencies I was curious. (I wrote my PhD thesis on mechanical vibration.) Brick diamond has a legitimate concern, but all I can say is that the decay is less than an undamped piano and as clean. This makes my OM very clean sounding which is good, but also fails to mask your mistakes!

I rarely take anything else out with me these days, unless I need a 12 string or banjo.
