These were installed on some MSA brand pedal steel guitars in the 1970's

Here's a schematic I did based on the photos, and a wiring diagram from MSA. I would use the same transistors as a BossTone, everything else is nearly identical between the two. Mike

I wouldn’t be a surprised if it wasn’t a Sho Sound Bosstone variant as those were quite favorable with pedal steel players (Buddy Cage being a noted user).
