i really do not care for 9 volt batteries and we have so many things that already run off of aa's . i was hoping to be able to run this unit off of a larger 12 volt sla cell i have here ? is that ok ?
how about a car battery or a deep cell , i have a few of those and we take those to the woods sometimes and have little jam sessions .its nice because i can recharge these and i don't have to worry about them running out all the time .
what about using an adapter , like a wall wort , is their an ideal voltage / milliamperage for this ? i know sometimes you get a hum when you use an adapter and that special ones , like the boss adapters for their pedals have a filter or something in them so they don't hum . is there a way i could implement a similar circuit in my Stella so i could use a generic normally "hummie" adapter and it would run quiet ?
what about methane ?
