I'm considering the possibility of designing an onboard preamp and then publishing the schematic on the Internet. Included in this project would be ordering a run of printed circuit boards and then making the bare boards available to everyone at my cost. Depending on how many people want these boards, cost would likely be anywhere from $3 per board up to $33 per board if it were just me. The actual cost would depend on how many we order. I actually started this project in the past, but then shelved for lack of time. Now I'm thinking of reviving it. Before I do, I''m asking for input. My goals are a very simple preamp perhaps without any tone shaping, but I know others might have different opinions. If you are interested building your own preamp from a bare pc board, what would your requirements be? I can likely make the circuit modular so that you can use as much or as little as you require. If this project interests you, let me know.
