I test every batch I receive before I sell anything. Yes, I hold quality in very high regards.
After receiving a big new batch I got tired of having to connect all the pots, switches and jack sockets so I realized I had to start simplifying the process. Besides the work it took it also costed me a small fortune in mechanical parts. Also, I wanted to create something that would be multipurpose and would also work on a bread board.
I started creating the PCB tester. It consists of two separate PBC's. One for the pots and one for the in- and output plus power.
In and output tester
This PCB has a built in regulated -9V, +9V, +12V, +15V and +18V power supply which is fed by a single standard +9V center negative guitar pedal power supply. It also holds PCB mounted In and output jack sockets and 2 footswitches . These swiches can true bypass 2 effects and the board also allows you to switch the order of the effects on the fly. It also has the option to place an effect between the input and footswitch. This way you can eg. put a buffer in between.
By using the pins on the 10 pin header mounted on the top of the board you can connect it to your PCB. If you mount pin headers instead of the in- and outputs you can test the PCB really easy. Buy some 40 pin dupont (as used for Arduino) and you save a lot of time testing the boards.
And below an example of a PCB ready to be tested with pinheaders.
This PCB saves me a lot of time. I only need to solder the components and some headers and it is ready to test.
Potentiometer PCB.
I also made a separate PCB for potentiometers. It can hold up to 7 potentiometers which should be enough for most effects. It works almost the same as the PCB tester. There is a 21 pin header used to connect the potentiometers to the PCB you are about to test.
Well, if you are interested, you can buy a set of PCB's for €20,- (not including shipping)

what the function of it?
It lets you test your DIY PCB's before you put it in the enclosure. It saves you time not having to wire the jacks every time.
