I am trying to plan my first build. a fretless with a cocobolo finger board. I have several specific questions. #1. are roundwounds too damaging to a fretless finger board made of cocobolo. I have a very nice piece that has a nice high pitched long sustaining ring when struck. #2 Should I do a zero fret on my fretless? #3 what is the minimum thickness for the body? (it will be neck though) what is a common thickness for a body? #4 do I need 2 truss rods for a 6 string, or will one due? I plan on using 2 carbon fiber reinforcement rods. and the neck will be a 5 piece lamination of 3 pieces of Jatoba and 2 pieces of Padouk Any recommendations on body/ top woods to compliment these woods I already have?
