The client needed a high headroom 16 input mixer to interface with his 3M M79 2" 16trk.  This was our solution complete with vintage RCA knobs, mute switches, pan switches, an aux send w/Pre, Post, and Off settings.  Very minimal signal path, all passive front end using , carbon comp resistors, super high quality pots and components.  All tube makeup gain stage, point to point wired.  The best of the 1950's meets a bit of 2015.  

Mute switches were a much needed late addition. 

In Session... sounds absolutely awesome.  So happy with the way it came out... and the client is over the moon.
