*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 require huge amounts 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 (such as the Pedal Power 2+ or BBE SupaCharger). You may get lucky driving them from the higher current outputs (5 and 6 on the ones mentioned). But a 100mA source will power them, as long as they’ve been ”started up” with a battery. So keep a battery in the pedal, and on power-up temporarily remove the adapter plug (to let the pedal start up) and then plug it back in – that keeps it going from one of the ”normal” outputs on your power supply. Obviously, do not feed these pedals any more than 9 volts DC – going higher could damage the charge pump circuit, and there’s no advantage in sound either, since the voltage reaching the circuit won’t change anyway.
