I would greatly appreciate some advice on finishing my walnut bass body. Although I have some experience finishing basses, I have never worked with walnut before. I am trying to achieve a very natural look with this bas and am currently planning to use a simple tung oil finish on the walnut body. However, I am unsure whether the oil alone on the wood will give me the deep tone I want. My question is: in building your basses, do you stain walnut before finishing with oil or sealing with varnish, urethane, etc.? Also, if I should be staining, what type of stain (water, alcohol, oil based) and technique would you recommend I use? Thanks.
