upright bass micing

[Zeppelin Design Labs]

If looks don't count, you could consider a balanced piezo contact pickup. We make this:

(we call it the Cortado.) This comes as a DIY kit. We wired two piezos in parallel to the balancing / buffering circuit and stuck them to an upright on either side of the bridge with masking tape. We were astonished how easily we got a terrific sound.

Here's a video that includes a few clips of how we rigged up the bass (at 1:42):

I see I'm posting years after the fact, but I'd sure like to know how the show went!
