I finally got a chance to test out my mics/jb3 in the field. The levels were fine.  I ended up running my jb3 at +2db and had pretty good levels.  Had to normalize a little in post, but not nearly as much as I did when I was trying to test my rig at home.

I taped about 2 hours, still have to pull it to my computer and mess with it with Sound Forge. From my headphones, the sound is pretty low (at +12 DB!) but I think when I use Sound Forge to normalize, I may be suprised.

ok, I took down the test show from my JB3 and made a couple wav smaplers for the experts to hear. Any help or suggestions would be great.

This was recorded at a local bar/ restaurant about 10-12 feet from the band right in the middle. I used a camcorder case (used to transport my jb3) as a mic stand on the table we sat at. The mics were about 6 inches apart and turned to the left and to the right (they sat like this  \  /  ).

I used the Giant Squid Cardioids and my JB3 with the gain turned up to +12dB like was suggested. These two samples are one raw and one that I normalized in Sound Forge 7.

Here are the links... (they were too big to attach to the board, so I uploaded them to my server).

Any feedback would be great.

Thanks for helping me get this far!

What kind of feedback are you after?  The immediate thing that jumps out is the lack of bottom end.  Things really drop off below ~150 Hz.  This is probably just the sound of the cardiod capsules in use.  Giant Squid says the specs are +/- 4dB from 100Hz - 12k.  You might want to do some eq'g to get that sounding reasonable.  To be honest, I wouldn't really consider that a 'music recording' capsule. 

As far as using a preamp goes, you had about 9 dB of room on the raw file with the JB3 at +12 dB so you'd do fine with a preamp  providing ~20dB of gain.  But if you're going to spend some money making things sound better those mics should probably go first.
