Our Boss CE-1 power conversion bypasses the internal power transformer and allows the pedal to be powered by an 18V DC power source rather than plugging into a 120V AC power source. This can be helpful for people that live in areas with different voltage standards or just for making the pedal pedalboard-friendly as it’ll be compatible with an isolated 18V DC power supply.
We’ve found that the Dunlop ECB-004 is a great option for our mods as it’s readily available and high quality. However, any quality power supply can be used if it’s:
1. 18V DC
2. Tip Negative
3. 2.1mm Barrel Jack
4. 100mA or higher
5. Isolated (no daisy chains or Y cables)
Another consideration for this project was the value of the pedal and preventing any permanent modifications to the pedal. This mod is entirely reversible with the stock transformer remaining untouched, the power switch wiring isn’t modified, the new power circuit (small, purple rectangle seen above) is mounted using pre-existing holes in the chassis, and the DC jack fits in the stock power cable hole.
