This Hiscox Hard Case for Gibson SG Style Electric Guitars is made from 1.5mm thick A.B.S. (Acrylonitrile Butadeine Styrene) plastic outer shell bonded to a semi-rigid polyurethane foam inner. The unique bonding of the inner moulding to the outer shell gives unbeatable, total structural rigidity which is UNMATCHED BY ANY OTHER CASE IN THE WORLD in this price range.Added to this is the aluminium valance, which extends deep inside the case behind the plastic shell, into which all the hardware (handles, catches, hinges, etc.) is riveted. This not only increases the rigidity of the case, but ensures a positive location of lid to base when the two halves are closed and greatly reduces the possibility of fittings working loose.With their incredible structural rigidity, all Hiscox 'Liteflite' guitar cases exhibit enormous crush strength and are tested to over 500kg.The case is lined in a soft crushed velvet type fabric which is bonded directly onto the shaped foam moulding giving a neatly tailored luxurious feel, perfectly fitted every time. With cushioned pads for the body and neck, your instrument is held securely in place.MADE IN BRITAIN!!
