Hi spacyman! I am going to move into a new studio rental space in Laval that's finally big enough to build a booth bigger than 5x5 lol

I had a couple of questions about the pine payer you put up on the wall :
- How thick are they?
- Did you screw them directly onto the drywall or did you use a resilient channel in between?
- Did you put some on the roof as well?
- Are they absorbent enough or should I add acoustic panels on top of them (Im going to be tracking vocals only)

I know this is an old thread, hopefully you're still active

Thank you very much in advance

Vince
