Dressed up in a black suit for the Blues, this isn’t your run-of-the-mill National Reso-Phonic guitar. Custom built to our own Paul Heumiller’s requirements, this M1 combines the earthy richness of an all-Mahogany body with the complex tonality of a tricone resonator (here housed in an antiqued brass shield)–giving this M1 a dynamic voice to bring extra color to your Blues or American Traditional arrangements. The neck features a smooth, round profile and has been tung oiled to be lightweight. Overall, the instrument is surprisingly light for a resonator, but still manages to crank out some seriously fat tone with great projection. Played in standard or DADF#AD with a slide, you’ll notice the presence of the middle registers, especially the A string, and the bright pop of the trebles. This M1 has an impressive attack, managing to be both focused and have a round edge, and will be hard (if not impossible) to put down.
