| Anyone ever use a 12 volt to 110 car adapter on a nashville 400, or other amps? |

| Well, my first inclination is that most of them aren't designed to handle the power. The second major concern is that they put out a "modified sine wave" (which is really more like a square wave) so the AC power to the amp would not be very clean. It might not hurt anything, but I don't think it's a good idea. |

Bob, the listed power consumption of the NV400 is 500 watts. I assume that is rated at the max output level. To operate at high volume, I recommend an inverter rated at a minimum of 1000 watts constant. When the inverter is supplying 500 watts, it is drawing ~40 amps from the battery. A 50 amp/hour battery would run it for ~ one hour. The time would be longer at lower power levels.
I have run small 20 watt practice amps on inverters with good results.
A gas operated generator would be more practical but the exhaust makes noise. You would want to put the generator in a location where the noise would not be a problem.

| Thanks,I was lookin for something to jam at the flea market with this summer .I had a buddie that had a honda generator that was fairly quiet but also fairly expensive.Some of those generators are pretty darn loud.I noticed a few new small battery powered amps in musicians friends that may be good for a little volume.Mabey I could set up a treadmill for people to exersize on and generate electric.If Mike sigler was a pickin, they would have to really get with the program. |

A year or two ago, some friends and I played a weekly jam at a local flea market. We connected our equipment to the normal 120 VAC, 60 Hz receptacles. There was no need for inverters and/or generators. No one complained about our use of power rather they were happy that we were there.
OK, get a good generator and set it away from your music site. We played a State Park here in western North Carolina where there was no available utility power. We used a (my) 5KW Generac and a 100 ft. heavy duty extension cord. If you cannot get a heavy duty cord, run two cords as most generators have two 120VAC outlets. It powered a NV1000, a Reno 400, and a 400 watt bass amplifier without any problems. Yes, there is exhaust noise but if you put it behind, and/or between parked cars, you can tolerate it as we did at the State Park. Make sure someone doesn't steal your generator by blocking it in with three parked, locked cars.
