If you were building the most upright-double-bass-like electric bass from Warmoth parts, what would your specs be?

Oh and: the piezo idea:
If using a UST you’ll need to compensate heavily with a preamp as well as an IR (piezo quack).
It would be better to use a UBT as an internal mic.
We need that top to vibrate and then reproduce it. I have an acoustic bass (Bolder Creek, very similar to a Tacoma), currently , not a DB. I was needing to play it unamped so went with PB strings. Now that gig is gone and I can amplify. Going to try flats and tapes with an acoustic IR.

I dislike how people keep referring to chambered bodies as hollow or semi hollow. They are not.
To be hollow, it requires different pieces of wood for the top and back: then to be joined by 2 side pieces. At times the top maybe supported by posts or trestles.

Thread Drift: That reminds me of how so many Alembic owners (or Alembic fans) refer to the Series I or II instruments as "chambered" or "semi-hollow" ...um, no, just because you have so many electronics in the instrument that you need to chunk out huge sections of the body on both sides of the bridge doesn't make it a "chambered" or "semi-hollow" instrument; you filled up all those chambers [sic] with circuit boards!
