I just bought a used Ampeg BXT-410HLF4 cabinet. The material covering the cabinet is something like velcro (the fabric of the velcro). The fabric is a bit ruffled all over, as if somebody took the wiry part of the velcro and pulled it on-and-off the fabric part a hundred times or so, leaving an unruly mess. Could I use some Wal-Mart-type electric haircut sheers to get the fabric to behave (i.e., cutting off the unruly excess)? Also, where can I get some replacement fabric for spots where there are holes? Thanks!
