    I have joined a band that plays all acoustic with the exception of me. We play on the streets about once a week and I have tried an acoustic bass guitar, but was drowned out (no surprise). I am considering a 3/4 bass, but the $ is an issue. Does anyone know of a battery or other power source that would power a small 15 watt amp for a few hours?
     
  2. Not a battery for an amp, but an amp that runs on batteries. Pignose amps.

    Pignose amps are 1/10 the wattage they are advertised at.

    Roland and Taxi are more honestly rated.

    You could use a small combo, a motorcycle battery, and a power inverter. The small combo should be class-d for the highest battery life.

    Or you can pick up cheap little power amps

    And power them off rechargeable batteries.
    No you can't bridge these little amps. A small cabinet with 4x8 ohm speakers, wire two to a side to give you 4 ohms per side. (Look at the Roland) The most sensitive (high efficient) cab you can find will save your battery power. i.e. Use pro-audio drivers - not car speakers.

    Can a Pignose Hog 30 keep up with a traditional bluegrass group? Does it sound like a bass amp?

  6. You could try a computer UPS.
    Don't know how long it would run a small amp, but with all the batteries, charging circuit, and transformer included it's certainly simple.

    I once powered a PF 500 for about 1 hour to an hour and half with a 450W(750 VA) UPS.

    That is the efficiency of class-d and smps
