With new technologies in studio equipment, hanging on to some analog pieces is a matter of do I really need these, or do I get rid of some? Plugins are getting better and better, and at a fraction of the cost of the actual pieces. There aren’t many artists who even care about larger studios to record their material. Maybe if a large project with multiple artists would be cool, but now a days, everything is pretty much done at home or a home studio. They don’t give you the wow factor that you may get in a larger studio, but the quality is still good. So for the engineers who love analog pieces, and have spent a fortune getting them, you may have a question about whether you keep them, or downsize and make something on the sale of a few of your great pieces. Personally, I’m a hoarder. I’ll just keep them all. But, you decide.
