A guitarist and I are working on a project to get a set list together and go busking before expanding to a full band and looking for actual gigs. Before we have our set list together I need to think about what I'm going to be playing on as we won't have power. I'm leaning towards using a car battery and inverter to power my practice amp as I think this would be most cost effective. I have a car battery charger so recharging would be no problem. I'm just wondering if there's any cons to the car battery/inverter set up that might make buying a battery powered amp a better option. Has anyone tried both set ups?
