Old School Big Muff Pi - Or Hold My Beer, I'm Gonna Try Something

I know, I know, yes - it's another Big Muff Pi clone. I like them, a lot. There will be more in the future. For this one, however, I decided to do something a little different. I'm still using the AionFX Halo board for this build - largely because I wanted a rock solid PCB for this experiment. If it ended up not working, I wanted it to be because of an issue with components rather than an issue with the board itself. The difference comes in my component choice. If you look at a lot of the early BMPs (like the one in the photo below), you'll see a lot of carbon resistors and ceramic capacitors. My first BMP build used older Allen-Bradley resistors, but all modern film capacitors. Later, I built a Ram's Head variant on a home-etched PCB - again with old school resistors but the capacitors were Panasonic film capacitors (not new by any stretch of the imagination, but not ceramic either). So this time around, I decided I'd try and go with ceramic capacitors across the board to see how the sound changed.
