The type of foam padding that Tuki Covers uses for their padded amp & cabinet covers breaks down after 15 to 20 years. When the foam padding breaks down, it turns to a black dust that leaks out of the Tuki nylon covers. The deteriorated foam dust gets all over your amp or cabinet. If you don't vacuum the deteriorated foam dust, when it gets hot, the foam dust melts, and sticks to the surface of your amp & cabinet. It's also bad for the environment!
This is the reason why I've decided to switch to Studio Slips. They use polyester fiber fill for their padded amp & cabinet covers which is high quality, durable, and safe for the environment. Tuki Covers uses foam padding that falls apart after 15 to 20 years, leaves foam dust that will damage your gear. When the foam dust isn't removed, it melts on your gear and becomes a fire hazard.
