Thx Bryan, it's a dead easy cheap fast finish, with a nice slab of wood like this I just rub in several coats of Danish Oil, sometimes with wire wool, then after a few days when dried and hardened I spend a night rubbing in carnauba wax for furniture/cabinet finishing - leaves a really soft natural semi-gloss, and easy to maintain. A lot of the manufacturers refer to this as 'oil-finished' and I really like the look on a nice piece of wood.
I think you hit on a great idea with the music collaboration - I'll have to see what I can come up with. plenty of other good guitarists on the forum here too, could be fun
