Effects Tester Mk II PCB

This board simplifies the testing process. Instead of having to use a breadboard, breakout box, or putting it all in an enclosure, just plug in your guitar, amp, and DC power. Then hook up four wires to your effects board (9V, GND, IN, and OUT). Now you're ready to test. It also allows for a trimpot to help you decide on the brightness of your LED. Once you find the brightness you like, use the tester pads with your DMM to determine the resistance. The Mark II now includes the ability to add an audio probe, charge pump allowing -9V and 18V, and a frequency generator.
