Fretgroove is a unique system created by Marco Bass Guitars. Fretgroove technology is patented and thus only available from Marco Bass Guitars. Fretgroove is, in simple terms, a hybrid fretted/fretless fingerboard. The bass’ traditional frets are replaced with sunken channels or grooves that give the instrument the feel and tone of a fretless bass but with the precision of a fretted fingerboard. When you play inside the grooves you have the fretted precision and when you play between the grooves you have the fretless sound. It’s a revolutionary idea that brings the best of both worlds in a single 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 growing tones, full of presence and depth.
Marco’s pickups have a very distinctive sound that is perfectly balanced as generated by the pickup and therefore does not need, as other pickups in the market do, any preamp compensation to enhance the frequencies that the pickup does not reproduce well. Marco’s own design has made it possible to squeeze humbuckers in the size of a traditional single coil. But size is probably the less important part of the innovation. Much more important is that this design makes it possible to have two independent coils, thus making the pickup switchable to single coil to obtain increased versatility. Talking versatility, even more important is the fact that the design allows Marco to tailor the pickup response to fit whatever the instrument and the customer needs. But undoubtedly the most important characteristic of the pickup design is the outstanding sound quality that the pickups generate.
