Just my 2 pennies...
After stripping 2 series 1's and 1 spoiler down to the bare wood, then reassembling, the weight of the finished instrument, without electronics and hardware, versus the bare wood
seemed pretty minimal by comparison to the finished body. I noticed much more weight gain by the heavy brass hardware, tuning machines and electronics than by any finish applied.
I will say that I have no idea how many coats of finish is actually applied with my projects, because often I sand through one to the next, but each bass has more than 10 coats applied. Don't think my work is as good as the work out of Alembic, but for me, they look pretty good.
I did wonder how an unfinished bass would sound? Chaos dynamics say it does.
Maybe the weight (11+ lbs)you enjoy is more of a property of the wood involved as opposed to the finish?
To Edofhuncote's note, there is some extra crazy happiness that comes from playing some of the best and most well made instruments in the world. 2
Question, Is finish really approximately 13 oz of added weight?
