Well Guys I Had to record into my DAT but, I could not opt to use the headphones to listen to the tracks in this particular case. I had to hear the Bass open to controll my Volume in each individual note played, heavy on the E and Light on the G etc... So Being broke from popping 700 in Strings this month I took A diagram posted on the Net somewhere on how to rig a Phantom Power supply to test drive different Electret Mic elements. Low and behold I modified the 5volt battery to 12 volt car key entry alarm battery, raised the resistance to compensate and doubled the Capacitance too, then I used a 3 dollar Pezo element from Radio Shack, Ripped the element out of the casing and shoved it under the Bass side bridge foot of my Bass . WAAAAMMM!!! Sounded like a million bucks compared to using my Sure Omni Mike. The Pezo was wafer thin under a 16th of an inch so the bridge height was not altered to bad, the Pezo is soft Brass so it bends to the contor of the Table and Bridge foot well. Of course I wont keep this setup it looks a tad ugly on my New Blond Bass, but it got me through the session at under ten bucks. I posted the diagram and Pic of the bread board for the curious seekers out here. Later Dudes. "I hightech Redneck with an Upright Bass, What next?"
