I just picked this work of art up recently in a trade. This is made by the one and only Ulrich Teuffel.
Top notch design, crafstmanship and finish in my opinion. Unique and ergonomic approach. Unlike anything else in my collection.
A few things to note. The body design going over the neck forces me to use better technique when playing the guitar, and I find sitting in classical position is the ideal way to play the guitar. I am historically not the biggest fan of Tune-O-Matic bridges, but this one being recessed makes it quite nice actually. This guitar has a certain "directness" to the notes that only a select few of the guitars in my collection share (Blackmachine B2, PRS Modern Eagle 1, Rick Toone S2). Very impressive!
