That's a G&L ASAT bass, made from the Opry floor. Cool. And of course Taylor has their pallet guitars..
As for recovered building materials, in this part of the world there is a lot of oak to be had, but it is some really HARD stuff! I've thought about using some on a few projects. You simply can't buy comparable quality at a lumber yard these days!
To me, road worn is simply a lie, just like autotune and lip-syncing to yourself in concert. Our world has been shaped by marketing to such an extent that kids just assume there is nothing else. *sigh* Now get off my lawn!
Having said that, I can understand not wanting to be the guy with the obviously new instrument when everyone else is playing instrument that have a few years behind them. Heck, I bought my Lakland so that I didn't stick out in an R&B (the old kind, not the modern kind) band playing an obviously modern Conklin or Alembic bass, and I've certainly been guilty of abusing instruments in the past (and probably will be in the future, but not the Alembic).
Ironically, my G&L (which I've shipped to The Bass Emporium to trade) is the most road-worn instrument I have recently owned, but the natural finish completely camouflages the worn spots and finish-checking..
