Simple Circuit Tester

As you know, you should ALWAYS fire up your new circuit and test it before you wire up your switch and box it up. Amazingly many people don't. Now there's no excuse...

This simple circuit emulates your final jack, power and footswitch wiring, so you can easily test your nice new build without much work.

Simply connect your four offboard wires for IN, OUT, +V and GND to this tester and you're ready to plug in and play.

The tester has the option to connect individual wires or plug in a Direct Connect ribbon cable (4 or 6 way), so should cover you for all standard negative-ground builds. For posi-ground effects you'll have to use the wired connections, but no biggy.

As everything is totally board-mounted on the tester there's very little to go wrong when building it.

Invaluable on any builder's bench.

Kit includes: PCB, all components, 3PDT footswitch, high quality jack sockets, DC socket, battery snap, LED.

Difficulty: Medium

PCB size: 50 x 50mm

Direct-Connect compatible (4- and 6-way)

Great tool! 5 product stars
"Just got this one. I put it together (very easy even for a novice like me) and tester a build I am working on. Really great tool. Now I know my circuit works. Very good to know before connecting everything." Henrik - 30/06/2018

Get one of these! 5 product stars
"This is so damn handy! It's well easy to put together, and also works on stripboard builds, it's much easier to use this than piddle about. Thanks Lee, just wondering if I can add anything to it as a mate designed a little tester for me too..." Mick Jones. - 04/05/2017
Very helpful 5 product stars
"This is an extremely useful tool for a beginner like myself. I've tested a couple of builds with it and have been able to quickly access that my populated circuit boards had no errors. I don't think I have need for the more advanced circuit tester but if I didn't already own an audio probe, I might have gone with that one instead." Clifford - 27/03/2016
