Ever think about tonal qualities of glue?? Glue can dampen your cabinets tone, so I like to use animal glue to apply amp coverings.
Cake or Animal Glue is the best glue for speaker cabinet covering
It dries with a very woody characteristic which drastically decreases cabinet dampening as compared to using most other adhesives. The resin or cake glue also is non toxic and has great work-ability, and it is much easier to stripp off than other glues, for it is water soluble and can even be sanded off. It is more expensive that other glues but is well worth the outcome.
