Eurorack Patch Cables

3.5 mm TS Mono

Boredbrain patch cables were designed with frequent patching in mind. The grippy and extra-flexible strain-relief makes pulling easy, while the medium-diameter cable is durable and drapes evenly.

  • Suitable for audio and control voltage signals in eurorack systems
  • Custom designed for exceptional feel and durability
  • Insulated copper wire cable with 3.5 mm mono phone plugs
  • Carefully packaged to prevent kinks


Why other cables fail – When copper wire gets worked back and forth over and over again, it becomes weakened and will eventually perforate. It’s as simple as that. The area at the back of the plug where it meets the cable is the most vulnerable spot. This is why Boredbrain patch cables were designed with an extra-long strain relief and are molded from a superior high-flexibility grade of PVC. In addition to its superior strength, this design also provides a large area to grip for extraction, so you are pulling the on the plug and not the cable. We guarantee our cables for life (as long as we are making them!), so rest assured we will gladly replace any failed cables with no questions asked. Now get patching!
