For sale: a custom adapter cable to power guitar effects pedals FROM THE 9V BATTERY CLIP INSIDE THE PEDAL.

This adapter must be connected to the 9-volt battery terminal located inside the pedal.

It allows you to power the effect using an external power source via its battery clip, without having to modify it.

The battery snap on the adapter is wired with reversed polarity precisely so that, once clipped to the pedal's battery connector, the pedal receives power in the correct orientation.

Ideal for vintage pedals that run on a 9V battery and either have no DC power jack or have a non-standard one — such as Big Muff, Super Fuzz and other classic vintage pedals.

COMPATIBILITY: Works with any pedal that has a 9V battery clip power input and requires a 5.5x2.1mm female DC jack — center-negative — to be powered from a pedalboard power supply.

Specs:

  • Input: 5.5x2.1mm female DC jack - center-negative - the standard for Boss-type pedals
  • Output: 9V battery snap connector (clip), wired backwards
  • Special wiring: the battery snap is WIRED WITH REVERSED POLARITY ON THE BATTERY CLIP SIDE, so that power reaches the pedal in the correct orientation
  • Total length: approx. 21 cm / 8.3 inch

IMPORTANT — PLEASE READ CAREFULLY:

This item does NOT work for powering a standard pedal from a battery in the normal way. This is a custom-wired solution by design, intended only for the specific use described above.
