Add a standard 1/4″ output jack to your pickup of choice without drilling a hole in your guitar. Mounts on the strings behind the bridge and points downward. This jack is made out of flexible and durable TPU material. Holds nice and tight.
The jack points downwards, so you should also run the cable through your strap to add some security from cable stomps. Right-angle cables also might be a good idea.
The best way to install it is to slide in one half under the A string, then rotate it 45 degees and slide the other side under the B string.
Works great when paired with a vintage archtop guitar and DeArmond pickup, but also works on other guitars with floating bridges like Selmer-style “gypsy jazz” guitars.
