Has anyone played a BG or ABG with this pickup system? I haven't but I'm in a very slow market location. If it's half as good as the ads say, it is sure to genuinely change sound, tone, dynamic possibilities for electric and acoustic or even uprights. As I dream and save up for a 6er (Okay John, maybe a 7 , I'm looking at this new thang and wondering if it may have b-i-g- influences in manufacturing. Y'all mind if I open up the floor for technical comments maybe from the luthiers or electro-wizards? Are there things we should be cautious of? This does seem to be a true innovation and not a fad, right? Compare Optical with Fishman? Just thought I'd start something new here. Cheers, all.
