PedalPower requirements
Blackhole9vDC, 500 mA (center negative)
H9, H9 Max9-12vDC, 500mA center positive 2.5mm plug.
Manufacturer recommends 500mA @ 9vDC or 375mA @ 12vDC
*Note: I have seen a measurement of 262mA @ 9vDC, but don’t know the circumstances (startup, playing or idle running, which preset, MIDI operation etc).
H909-12vDC center positive
Pedal says ”12W”, which comes out to 1.33A at 9vDC and 1A at 12vDC. Actual current draw has not been measured (yet).
