the nos cab is warm, wide and very full sounding. Its also sounding pretty same wherever you step around your stack not like cheap cabs that sound awesome in front of them and just weak when you go some footsteps ahead. Also it works good with V30 but you can have it loaded with g12k, greenbacks, g12h, v30 or eminence tonker /governor.
They are inded built like accoustics with a separation inside. For info the cab on the picture is an oversized 2*12. Good stuff, solid built, good price used and ok price looking on high end brands (a nos 4*12 is around 1000 euros new against the same for mesa that is about 1200). I had a mesa 2*12 and a framus on the same head before the nos cab. The nos wins hand down, better projection, more open sounding, holds lows same as mesa but delivers good sounds on low volumes and the cleans are really good unless the mesa cab that made cleans sound really boomy and cold to my tastes.
