This project isn't dead. It just took a little longer than expected because life got in the way. The first rendition is finished. I'm not completely happy with it but it turned out fairly well. Everything is currently set up for full stereo but I accidentally purchased mono 3.5mm jacks. Also, I suck at drilling so some of the holes are off center. Current version has 3 ins, an aux send, and a headphone out. The aux send can be patched back into one of the inputs for fx. It runs on two 9v batteries but I could easily add a dc in. I don't think I'll be selling any anytime soon because I don't feel comfortable putting these out until I'm 100% happy with the design and I'm in the middle of moving so I don't have time to be assembling mixers.
