*A note about the Maxon pedals with internal 9/18 volt operation (the Pro and Pro+ models, VOP-9 etc) and those that have a charge pump to stabilize the voltage at 9 volts (OSD-9 etc): These pedals draw lots of current for the first few milliseconds, and then settle down to the listed current draw. This means they may not start up with a 100mA power supply/output. You may get lucky starting them up from higher current outputs (250mA or more). If you don’t have any higher current outputs available, one way to get around this is to keep a battery in the pedal, and on power-up temporarily remove the adapter plug (to let the pedal start up from the battery). Then plug it back in, which should keep it going from a 100mA supply.
**Another note, now on the ”Real Tube II” series. The current draw listed is with the pedal up and running. At powerup, these pedals have a much higher inrush current (upwards of 2000mA). They will work from a high current output (rated clearly above the stated current draw), but the more you can give them, the better.
* ** Never feed these pedals any more than 9 volts DC – going higher could damage them.
