There have been a few discussions about pedals and pedalboards lately and it SEEMS as though most players aren't really using batteries anymore but instead are using either a stand alone power supply or a multi-output (and sometimes multi-voltage) power supply integrated into their pedalboard.
These days, how important is it that a pedal operate from a 9V battery (acknowledging that some simply can not) and is it worth paying more for a pedal that can support battery operation (even if it means <20 hours of battery life)?
As a follow-up, how many of you guys would suggest that the days of using 9V batteries is coming to an end?
I'm looking for comments from a player's perspective, one who uses amps and cabinets and not somebody who mostly uses them at home with their studio.
