THE BIRELI LAGRENE BL6

The BL6 is a fully hollow archtop guitar featuring a carved, hand-graduated spruce top and carved flame maple back and sides. With a slim 44mm (1.74”) body depth, a 400mm (15.75”) lower bout width, and a florentine cut-away, the BL6 ensures easy access to the upper frets, catering to Lagrene’s dynamic playing style. The guitar boasts a one-piece flame maple neck with a soft ‘D’ shape, a flat radius ebony fingerboard, a 43mm (1.69”) bone nut, a 635mm (25”) scale length, and 22 frets. Equipped with a handwound OX4 and a Kent Armstrong Vintage ’57 humbuckers the BL6 offers a robust electrical configuration. Finished in deep cherry nitrocellulose lacquer, the BL6 is as visually striking as it is sonically versatile. It is a ‘feather' light guitar with a resonant tone unplugged and dynamic performance when amplified.
