As an avid junque collector, recovering amateur radio operator, cheap Scottish bass (re)tard, and good ol'e farm boy, one of my frequent cures for G.A.S. entails hauling out the soldering iron, and digging into the collection for bits and pieces. Of late I have been feeling a certain depression, due to envy towards those acoustic guitar players, banjo pluckers and fiddle friends, with whom I jam, more or less weekly (sometimes weakly). They just whip it out, check the tuning, and they're off to the races. I have to set up an amp, find power, etc. Minus one to spontaneity. I admire the double bass players, however I havent enough time, or money (see cheap note above) to buy and learn a Bull Fiddle (would if I could). I have looked at the bass acoustic guitars, however they mostly seem to vanish into an acoustic void once the banjo winds up and the martins set to strumming, unless you use an amp. Meet the new boss.... The problem is not the usual indoor shows and practices. Plug-ins are plenty, and I can usually arrive early. When summer comes, and the music moves outdoors, busking on main street, or in the park, the system breaks down for me. I have tried running my practice amp on an inverter and battery, but things buzz, and there are even more wires to deal with. And some places even have a no amplifiers rule, if you can believe that !!!!? Hmmmph. There are battery powered amps available on the market, but those with any output or stamina are way out of my fiscal ballpark (see cheap note above). I was digging through the Junque, looking for a part for my buddy, when I saw IT! In one gestalten flash, I saw the future, an answer! I forgot my quest, told buddy I didn't have one after all, and pulled out the graph paper instead. Over the next day or two, I assembled a small pile of components. A piece of drain pipe, some scrap 3/4 inch wood, a pair of heavy duty 10 inch woofers (8 ohm, ~100 wrms, 1 inch voice coil) from ported hi-fi speakers, a 12 volt gel cell worthy of robot wars, and IT! IT was an older car stereo amp, about 50 wrms/ch. It sounded very nice in my old K-car, twice removed. I first tried ESP's simple bridging solution (phase splitter), to make it mono, but it started sounding a bit raspy above 20 watts or so. I tested it in stereo, and it was all good. So far so good. Next I modified the phase splitter into a flat preamp, and tested with the Fender beast. All good, although the dummy loads are smoking a bit on the low B. So far the only flaw in my plan is that this thing will be as heavy as a 100 watt combo amp, plus the weight of the battery. At least it will be cordless, wireless, and easily hidden. Gotta find some wheels.... Next stop, the woodshed. Stay tuned. Should be some pictures coming soon too!
