The Dynamix is NOT useless in this setup, in fact it is a great choice for a more west-coast type of audio processing, it's two transistor based LPGs with overdrive and sidechain compression, and can even be used as a VCA. Also, I wouldn't recommend anything from synthrotek, especially not their power supplies which are known for catching on fire. There are plenty of better DIY options out there, including one from Dreadbox(https://www.dreadbox-fx.com/hades-diy/). I would recommend looking at modules by RYO, 4ms, befaco, bastl, and particularly Frequency Central, who makes a whole line of SH-101 clone modules.
