any of you guys ever play with a centralized battery bank as a power supply for your pedals? i know there are folks out there who dont like 120v power supplies, just wondering if any of you have tried it.
Yeah, I have. Takes up about as much space and weight as all the wall warts but eliminates most of the hum problems involved. I had one which would last about 5 hrs on a charge, but could be plugged into the mains to charge whilst being used. Use NiMH batteries - good value, safe, high capacity. The only batteries with better performance are Lithium, but they can show severe memory effect, can't charge and be used at the same time, and occasionally explode.
