Where to go to test my busking guitar amp
guitarRig.png md5: 21c2ffda...
I am jerry-rigging a 40 watt guitar amp up to a 750 watt inverter connected to a 12V LiFePO4 battery. There's other effects pedals too. All run off the inverter. Need suggestions on where I can go to test this out with the volume cranked while running a decibel measuring app on my phone to get some idea of how loud the 55 yo 85 decibel volume is. Some kinda wide open space where no permit is needed so that its still legal to try it out there would be ideal. Any suggestions on where to go other than some beach that nobody visits?

Lots of amps use 18v. Tools and laptops use 18v. It's completely pointless to switch back and forth between dc and ac and dc again.
