The spiritual successor to the one that started it all, Socialist Jr. does the "Brutalist Jr. thing" but with a number of improvements and additional options built right into the PCB.  If you're planning on building a highly modified Brutalist Jr., the Socialist Jr. will get you there faster.  Here's a quick summary of the changes:

  • Moved I/O pads for easier wiring.
  • 2nd op amp stage converted to non-inverting to improve bias and make it tolerant to a wider range of dual op amps.
  • Gain converted to a dual pot to control two gain stages simultaneously resulting in a much wider range of useable gain settings.  (cleans up better) Values scaled to make this work well with readily available, B100k dual pot.
  • "Response mod" pot built in.
  • "Clipping mod" switch built in.
  • Deeper mid-cut with Loudness fully engaged.
  • Less volume drop when Loudness is set at minimum. (tone-stack bypass)
  • "Mid Shift" switch built in.
  • "Bright Switch" added.  This was not a common mod in the Brutalist Jr. but it's useful for removing sizzle when loudness is fully engaged.
