The surprise of NAMM for me was the reintroduction of the Gizmotron. Something that Godley & Creme of 10cc fame made back in the 1970s. It never worked that well and kind of disappeared becoming almost mythic. Well the patents have long lapsed and then some guys in New Jersey bought the name of the company and started redesigning it from the ground up. It now works and is for sale, it should be out in a few months.
Sounds great! I wonder if it would work with acoustic strings as well. I remember Paul Horn using his flute to vibrate the inside strings of a piano in the 70s to create an infinite sustain without the flute being audible. Maybe back then they just used highly amplified contact microphones.
