The G-112A features a new hard top designed to support the amplifier on stage. This allows for better sound projection. The top of the case has support rails to keep the amp from vibrating off during the performance. The exterior is constructed from rugged 600-Denier Nylon over a 1/2 inch wood frame. The interior is padded with 20mm of high density foam covered in Tricot for ultimate protection. The case includes rugged, reinforced web side handles for carrying over rough terrain plus a large accessory pocket for pedals, cables and gear. The G-112A comes equipped with heavy-duty wheels and a new and improved pull-out handle with a crush guard, making this a great case to transport and use all at once.
