Hi - I've been building some stompboxes from layouts on this site for a few months now and have had a lot of fun and some good results. Thanks!!
One of my bandmates asked me to build a box to mute his K&K Golden Bullet Mic, since the box supplied with it has no controls. I ended up making him a box that re-houses the K&K power supply, has a popless mute for the little K&K condenser mic, and a mute for a second circuit so he can connect his pickup output through it as well, and mute both mic and pickup at the same time.
In order to achieve a popless mute on that mic, I ended up finding a mute circuit here that works well:

But of course the most important part is "what does the box look like?"
