I'm in a 7.5' x 10' x 12.5' room with my huge desk that takes most of one short wall, piano, drums, three guitars, bass, guitar amp, LARGE bass amp (Yamaha B100 on a Peavey 1820) + bookshelf and filing cab and a huge OSS boom stand that can telescope out into almost anywhere in the room....and I have more gear out in the shed that I need to fit in eventually (some old rack gear, drum throne, more mike stands, etc.)! I still need to build a small mike locker (and put a few in it!), get a decent guitar amp (orange/mesa/blackstar, maybe marshall, I dunno yet). I love my room, but it's not an ideal studio situation. Would make a great mixdown room, but for tracking/performance/mixing/mixdown/mastering it's not perfect...
