I'm looking to make myself a Warmoth Jazz. I'm thinking of going with the walnut body below and I'm going to oil the whole thing - body, neck, fretboard, etc. Natural finish and ease of application. What kind of neck would look really good on this? Maple? Rosewood? Pau ferro? I've pictured a neck below - would the two look good together? Also, I have a J-retro to put in - what kind of pickguard would look good against oiled walnut?
