Martin Blackwell guitars are maybe among the very best concert guitars you will find. Famous players such as Gabriel Bianco and Mark Teicholz both GFA winners play on his guitars. Martin initial model was of course Matthias Dammann guitars. We had the chance to compare a 2015 Dammann and a Martin Blackwell and we must say that Martin ‘s guitars have something special that gives the player the feeling that his guitar is really without any musical limitation. All the musical intention are easy to express. The notes are thick and warm but still with the possibility of clarety.
