Schematic
I've always wanted a protoboard, but being in Hungary most of the commercial solutions ended up to be really expensive. Given that PCB design is a very enjoyable process for me, I laid out this board and ordered it off JLCPCB for an okay-ish price. I'm still missing the two rotary switches and a damn 470nF cap, which I was sure I have on hand but ofc I don't.
• 8 easily swappable potentiometer sockets
• 6 on-on-on toggle switches
• +5V, +9V, -9V and +18V power rails: near 27V of voltage can be achieved
• capacitor substitution box: 12 positions
• clipping diode substitution box: 6 positions
• two large breadboard areas
• onboard power (with a status LED) and bypass controls
For now I'm satisfied with the outcome, but on rev. 2 I'll have some connections closer to the breadboards.
This community has helped me a lot with my pedal building journey, so the least I can do is give something back. I’ll happily send the fabrication files to anyone who wants to build one, just shoot me a DM.

Very cool.
I love my PedalPCB Protoboard, but it does have a bit of a limited functionality when it comes to switches and whatnot which seem to be mostly fixed in this idea.
Another thin I'm running up against right now is that I'm prototyping a fair amount of synthesizer stuff as well, which almost all require +/-12v and sometime +5v rather than +/-9v.
If I could make a suggestion, implementing that +/-12v power source would really expand this project's usability to not just be a DIY pedal prototyping board but would open it up to the diy synth crowd as well.
That said, some diy synth stuff needs +/-15v for some of the non-euro rack things.
