with a low power consumption? I'm thinking of the EQD Speaker Cranker, which they specify as having a mere 2mA power draw. I should think a battery would last a very long time in that pedal - but does anyone have experience to have more than a guess? I know it's going to be dependent on how much usage it gets... so I'm hoping for an estimate in hours. What about something like a TC Electronic Polytene 2 - listed as having a 45mA power draw?
