Studio Gobo DIY Design
Drum platform and overhead trap
This design can be used in a live or studio application. For both live and studio you have an option of building a front drum surround which is what I recommend for live. In the studio you can use a drum surround to block the drum bleed into the studio area (if you are recording a full band). The drum surround is a separate download.
Booth Design
Build the same as above but add plexiglass to the top of the drum surround.
Drum Surround DIY Design
This design is for a stand alone drum surround.
Options for this are to build it with the above drum platform size in mind and add plexiglass for the space between the top of the drum surround the the drum platform canopy.
Studio Gobo DIY Design
Here is a gobo design that I put together for a home recording studio. It can also be used for live applications (drum surround).
The most important part of the design is the use of "Quietrock 525" you cannot scrimp on this, it costs about $65.00 per sheet (4' x 8') but it makes all the difference.

The 22.5° ends of the design helps to create various configurations, by flipping them around you can create straight walls or as the picture shows create a surround. If you need a reflective surface on one side don't do the 22.5° ends, instead make it square and replace the fabric on one side the gobo with 1/2 plywood. This will give you a additional room tuning option, you can move the gobos around and have either the reflective surface or the absorbing surface exposed in your room.
