Hello, I have a metal dc jack that shorts when I plug in the adapter but when the jack isn't attached to the metal enclosure, and is free floating, the pedal works fine. Also, there are 3 solder posts on this jack. What's the 3rd one for?
Besides insulating the jack from the enclosure with shrink-wrap or something, what's the best approach to fix this? I'll probably be using the plastic insulated jacks next time. Thanks in advance!
You may be able to find insulating shoulder washers that will provide the isolation you need.
The third terminal is likely for a battery switch. When you insert a plug into the jack, it pushes the switch open, disconnecting your battery (if you opt to use one).
Welcome to the forum!
The best approach is to not use it at all, IMO. You might be able to insulate it from the enclosure but it's a failure point waiting to happen. The third solder tab is likely for a battery + connection.
Yeah, I'm going to defer to Brian's suggestion. For the cost of the shoulder washers with shipping, you could simply buy a plastic DC jack.

Makes perfect sense, I'll just grab a plastic one, thank you both for the swift replies. I just built my first Madbean pedal, Weener Wah, and it's superb! Side question: (Maybe should be a separate post) But how does The Laureate compare to the original, and is it based on the 1993 Natural OD?
