Basement recording studio in Columbus Ohio Build Diary

I was planning to do 2 layers of dry wall, is OSB expensive? I am trying to go the cheepest route

Probably a bit more than drywall, but not a huge amount. Check prices in your local Home Depot (or equivalent).

I was thinking putty pads similar to ... Would that not work?

You can do that if you want, but it's a lot of extra work to cut all those holes, beef up with putty pads, seal carefully, etc. Doing one single penetration then surface mount everything inside is much easier. And faster. - Stuart -

long time no see! This studio was designed by our forum member Glenn “gullfo” about 5 or 6 years ago. For many reasons it was postponed. In April I decided to pick back up where I left off and as you can see we have made great strides. All of these updates are posted to our Instagram page @arcadiaaudiohq. Glenn has been amazing with holding my hand through this. Thanks John Sayers community, without this site I would have never made my dream a reality. More updates to come.
