decided that I had outgrown my old test rig and wanted a more streamlined all in one more flexible solution. Built the jmk testing rig and added a variable voltage ala madbean test rig via a road rage board I had.I decided to cram 10 pounds of shit in a 5 pound bag and stuff it all in a 1590bb box. the only road rage i had was a bypass board so that made it a tighter fit. added a 12v tap wired off the 15v with a 12v regulator wired in series. love this thing. sharpie labeling ftw!

That's awesome, man!
It may just end up being your most-used pedal!

Jmkpcbs.com or did you mean the charge pump?

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

That's pretty awesome yo. Just keep in mind that a charge pump isn't regulated. You would need a regulator, but I don't know how to do that.

The 12 and 15 volt taps are regulated because they use regulators. 18 volts is unregulated. But for simple testing and biasing before boxing it shouldn't be an issue.

The test rig is from jmkpcbs.com and the voltage selector is the madbean road rage board. All instructions are in the build docs for each pcb. I just painted by numbers haha
