I'm just using the mic amp board as it comes with a dynamic mic and levels look good but there's the option to add trimmers for both the compression and noise gate level. I have an output gain control knob in there.
My rudimentary metal work skills are slowly improving and I'm quite proud of the nibbled hole for the LCD display in this one. My nibbler has been sticking, which was frustrating, but a little WD-40 did the trick. I learned from a recent Adam Savage video that WD stands for "water displacement".
