I've added sound-absorbing material in place of the foam padding in an effector case I bought at Shimamura Music. I've been using it for about six months, so there's some wear and tear. * Includes Velcro tape - Type: Effector Case - Brand: E.D.GEAR - Internal Structure: With foam padding (homemade) - Color: Black - Size (Internal): Width 350mm x Depth 260mm x Height 100mm - Handle Material: Resin Large, durable metal fittings are used for strength and durability. A large resin handle is used. It's easy to grip. You can also put stickers on the outside.
