I have officially retired one of the racks, the mixer rack with the preamps in it. It was a good design in some ways, but it was not even close to portable enough. I now have a laptop for mobile recording. I still have 16 track capability, the same as before. I can provide several custom headphone mixes, and I still have the same mics. All is quite well.
I’m now working fulltime for RealTraps as well. So I spend a lot of time thinking about how to achieve good sound. :-)
