Wisdom? Someone on the Forum knows more than me on this? Really?
Well, Rosewood or Morado, the thickness spec should be the same.
Some refinish. There is no 'some' with this finish. It all has to be stripped and re-finished.
In my opinion, the cost of this job done professionally might cost more then the bass was new which was probably about $1100-$1200 in the early '90s.
I hope this helps but is you are seeking Wisdom, well, I can't really comment on that past what I already have.
