1 DCBirdMan 11 months ago Well after over 30 years, my pals Dave and Joe are closing Invisible Sound Studios in Baltimore. Just what you expect -- The Effects of The Modern World causing this-- fewer people using a recording studio, and music trends in general. They have over 100 vintage amps and even more cool old microphones going up for sale. No guitars I am aware of, but some cool old keyboards, tho and big stash of drums. 1st pass is just former customers and friends going in when it starts in a few weeks. I got my eye on a Magnatone 213 I sold them over 20 years ago., There's no list of gear/prices that I know of. It's possible leftover items will be sold online but not sure.
