FretGroove is a unique design created by and exclusive to Marco Bass Guitars. FretGroove in simple terms is a hybrid of a Fretted/Fretless fingerboard. The bass’s traditional frets are replaced with sunken brass channels that give the instrument the feel and tone of a fretless bass but with the precision of a fretted instrument.

Matched with Marco’s custom hand wound pickups the FretGroove bass goes beyond the fretted/fretless bass medium and creates a unique and artistically expressive instrument with sounds ranging from mellow and woodsy to bright and growling tones full of presence and depth.

All Marco Bass Guitars are available with 4, 5, and 6 string FretGroove necks.
