FAQ: My pedal lights up, but all I get is loud humming and noise

If you plug in your pedal and the LED lights up, but all you get is noise/hum or total silence from the unit there is a 99% chance you fried your circuit board with the use of an incorrect power supply.

Pedals are simple, they dont require any exotic power supply…  BUT you can’t just plug any fucking power supply that fits in the hole.
ALL Pro Tone Pedals operate on a 9volt negative tip power supply. We recommend the Godlyke PowerAll, but there are literally dozens on the market.

WARNING- do not use multivalued interchangeable tip power supplies. These are not designed for audio circuits and are REALLY easy to set incorrectly and damage your pedal.
