This project can be used as a blueprint for making simple preamplifiers for contact mic's (or other stuff). It's put together to allow you to experiment and find unexpected joys.
If you want something that definitely works well, there are simple recipes to follow. If you want to stray off of the map, you can substitute components and see where they lead you. The experimental approach won't always work but I've had surprising, non-linear, results that have been fun to work with.
The Contingent Piezo Preamp grew out of a research project. Whilst investigating common contact mic preamp circuits found online, I noticed a common pattern and wondered if I could design a kind of meta-schematic. I also mucked around when testing circuits and was surprised that many still worked even if I veered from the schematic values.
This is the result of those investigations. I can't guarantee the best preamp but half the fun is in trying new things ✌️??
