So here's the deal: a while ago I had the chance to buy a stripped no-brand guitar cab, tolex in great shape, for 50 ($65). I've always loved the look of those big-but-not-too-big 4x12s, so this looked like an opportunity to turn this thing into a bass cab! Needless to say, I've got some questions. I'm away from home at the moment so I can't get any pictures up here, but what I can do is give you the specs! 4 12" speaker cab, looks like a Marshall cab Made out of really dense particleboard (which, I've heard, is not ideal but not a dealbreaker either) No wiring Basically open backed (makes no sense for a Marshall-style AFAIK), there's a 100mmx740mm (3.9"x29.3") opening at the rear, near the bottom. Pre-cut for Orange/Markbass/Marshall style recessed handles Dimensions: 750mmx740mmx285mm = approx. 158L (29.5"x29.3"x11.2" = 5.4cft), there's also some internal bracing, so perhaps a litre (approx. 60 cubic inches) should be substracted from the total volume I plan on using this cab with my Little Mark II at the moment, but may decide to hook it up to a currently nonexistent all-tube amp. I'd prefer to keep it on a budget however, so I'd like to spend no more than 300 (that's about $390; also sound > looks, I'll leave the grillcloth for now ). I can pretty much guess straight away that I'm going to have to spend some time sealing this cab. Anything else, I'm open to suggestions! Speakers, switching, ports... any ideas?
