To protect your new GB-4000 and SR-4 amplifier while you travel you should consider purchasing the Deluxe Compact Travel Case. Because of its small compact size it can be shipped to almost any country through the USPS. This is the "Rolls Royce" of instrument cases, constructed of heavy-duty yet lightweight ABS, the case has metal-reinforced corners and a strong frame for years of great performance. Its interior has adjustable dividers for a secure, tailored fit for your GB-4000 / SR-4 amplifier system and all of the cables and accessories. It's also the right size to 'carry-on' and stow when travelling with the airlines. The travel case also includes bottom feet, a removable shoulder strap and dual locks with two keys. Inside dimensions: 17 1/2 x 12 1/8 x 6 (inches). Outside dimensions: 18 3/8 x 13 x 6 3/8 (inches). 7.93 lbs. The Deluxe Compact Travel Case is not returnable due to the nature of how a travel case is used, it (and the container packaging) cannot be restored to new.
