Harley Benton’s Progressive series has already earned its status as a “golden oldie” on the bass market. The recipe for its success is simple: remarkably high quality workmanship, first-class components - and a great price! Two punchy humbuckers and active electronics are controlled using bass and treble controls that let you dial in any number of useful tones. The Canadian maple neck is bolted onto the alder body - a classic tone wood combination! The shaping fits your body perfectly, letting you run riot across the 24-fret black walnut fretboard in comfort. Deep black dominates every aspect of this instrument, highlighting the “Tai Chi” fretboard inlays for an exquisitely refined look!
