Once that is done I will send the engineering files to the PCB manufacturer to make an initial batch - probably 10 PCBs for now.
Nice, I remember the old days of rubbermaid tubs full of etchant as a kid in high school. So primitive.

Yeah, that was me 10 years ago when I made the first LauriePedals.
I use these guys now:

The last lot of boards I had made were for a modification to my pinball machine. Fast and super good quality.

Good Lord, what a brilliant bit of technical know-how and explanation Laurie, nice! However a little voice tells me I need to know two things...does it sound epic and what colour will it be in!

Thank you.
I do think it sounds EPIC. When I hook the guitar up to the prototype it makes me want to play...
Colour? It's an overdrive, so I was thinking yellow, of course

This is the prototype on the bench. It has been running with overvoltage supply and super hot input for 2 weeks continuously now. All is well, Sounds exactly the same as when it was turned on.
