My project is going to be (once I'm able to get to my tools) a six-string bass (probably fretless). However, before I begin, I have a few questions: 1. Since it's going to be 38" scale (I know, I'm crazy), what kind of truss rod would I need? 2. The goal, aside from making it sound nice, is to make it as light as possible. What kind of bridge would help? 3. The 38" scale brings up some additional neck questions: How long will the neck have to be, and what would be a good width at the 24th fret equivalent? 4. Anything else I missed? Believe me, I will take ANY suggestions.
