Good point.
Carry on, but buyer beware. I’m a member of a HI-Fi site where, because “enhancement stuff” like this are major advertising contributors, you disrespect even the most ridiculous stuff at your own peril. They’ll ban you for even suggesting a published double blind test showed no difference in sound. They consider it “argumentative”.
I’m not a contrarian. I spent the better part of last night listening and reading about the device. I don’t think there’s any question that it registered a difference in the sound of the guitars played esp the new ones. I recently purchased a D-18 Martin Golden Era 1934 (made in 2008). It’s a great sounding guitar, that’s why I sold it and upgraded to an affordable D-18 authentic. I can’t wait to get it and see the difference. Many people say there is very little to no difference. This makes sense if the guitars are relatively new.
I thought there would be a lot more guitar and violin players on this forum.
