evening all, First time post here! I've tried searching all over the forum if anyone had posted any info on the described topics but found none so here it goes. I live in an apartment and have a tube rack setup with a marshall 1960 4X12 cab. Has anyone tried to build an enclosure to dampen the volume and record with it? My Idea was to build one with soundproof foaming inside hopefully not to get any feed back at louder volumes. Any advice would be greatly appriciated! Thanks!
