Note: These current draw figures (250 and 400 mA, respectively) are not measured actual draw, but the minimum power supply capacity recommended by UA. When/if I receive any measurements of any of these pedals – or break into my piggybank buying some of them myself 😉 – I’ll of course update the list with more precise numbers.

All pedals use 9vDC, center negative w/ 2.1mm plug. Using a separate/isolated power source is also recommended.
