The Hagstrom Jazz Model HJ-600 Semi-Hollow Electric Guitar features a spruce top, contoured flamed maple back and sides and maple set neck. The Hagstrom patented H-Expander truss rod provides tension at either end and runs the entire length of the neck. The rigid yet lightweight alloy truss rod allows for very low action and a thin neck.Another Hagstrom exclusive, the resinator fretboard is an extraordinary, homogeneous wood composite that maintains a strong fundamental harmonic and eliminates wolf tones. It offers the articulate sound of high quality ebony but with more consistency and durability. Silky smooth, reliable and fast.Two Hagstrom HJ-50 humbuckers, each with volume and tone, combined with the hollowbody resonance, give the HJ-600 incredible power and range of tone.The self-lubricating graphite composite nut is much harder than bone or plastic resulting in more string vibration through the neck.
