Most of the guitars from the Walter workshop are in the Humphrey "Millennium" style. Walter was one of a few guitar makers granted permission by Thomas Humphrey to build in this style, and Walter played a Humphrey for many years and from it took great inspiration. The true Millennium design is more than just an elevated fingerboard, but rather a complex geometry that adds to the projection and character of the sound in addition to facilitating upper position playing. Sound ports, which many players feel enhances the volume and fullness of the sound, are optional.
These guitars utilize Walter's Defined Resonating Area concept, which restricts primary vibration to an acoustically optimal area of the soundboard. This allows for a beautifully clear and focused sound, with an exceptional amount of clarity and color. It also allows optimal bridge placement for either the 650mm or 640mm scales without sacrificing volume or character. An all wood lattice system is used for bracing.
Walter traditional guitars use the instruments of the Hermann Hauser legacy as a point of departure, focusing on the character of sound, how it blends and separates, and how each of the registers sing. These guitars have a remarkably intimate character yet also project strongly in a concert setting.
These guitar can use either the Defined Resonating Area with lattice bracing, or a more traditional fan brace system.
