What are the power requirements for the OB.1 pedal?

For OB.1, we recommend a 9V battery (included inside OB.1) or any 9VDC center-negative power supply (not included). Some switching supply adapters (1 Spot) have been found to be a bit noisy with OB.1 and are not recommended. Our own Ojai and Zuma power supplies work well without additional noise in the audio.

OB.1 consumes less than 20mA of current.
