    Most of you may recall my attempts to make a portable bass guitar cart that can be useable outdoors in a high school marching band. My original cart used a Trace Elliot 4x12 cabinet with a BBE BMax into a QSC amp. We also use an AKG wireless (Airbud?) system. My second cart uses the same BBE/QSC1450, but I have split the signal from the BBE into a Rolls crossover, then one channel of the QSC powers a Fitzmaurice Omni10, and the other side powers a Fitzmaurice Tuba24. I was able to test the system today, and it rocks! Literally shaking everything around it. I will test it outdoors soon. Here's a photo:
     
  2. that looks funk-tastic.

    how are you supposed to get power to it out doors in the middle of a football field?

    Full disclosure, I'm a certified Fender technician working in a music store that carries Fender, Yamaha, and Ibanez products among others.
    At Yuma High School I marched in parades with a '68 reissue Fender J and a Peavey TNT 180. It was on a three-wheeled cart, pushed by a flag girl, and powered by a car battery through an inverter. Worked out great until my junior year when we had enough tuba players for a tuba section.

    In 1979, I joined my high school marching band, on electric bass. Pretty much the same sort of thing. A big cart pulled by two other kids. Traynor 88 Watt bass head and 18" folded horn. Car battery and inverter.

    I refused to play in the rain, which meant that I went on the field exactly once. Then, my marching band obligation over and done with (it got me out of sophomore gym class), I ditched it.

    I've heard marine batteries are better suited for this type of application (whereas car batteries are better for huge current discharge over a short period). Anyone?

    Probably true. You will also notice that I spent a fair amount of battery juice on running the heaters of those 6CA7 tubes. Battery operation is probably a good use for a switching amplifier.

    The cart is powered by an all-in-one rechargeable 1500 watt invertor on wheels (deep cycle battery probably). It worked great last year. Never a problem. Rain was a concern, and we packed a cover, plus the wireless system was there as a precaution, too.
