Clayton- just a single coat of epoxy, brushed on, sanded and buffed out. A few months ago I ended up sanding it all off the top and tung oiling it, to see if it affected tone at all--it did not. Changing the neck materials changed the sound noticeably, though. See pic below (the mahogany is under epoxy.)
Jordan- The bridge, saddle, and nut are lignum vitae. I used a Fishman under-the-saddle piezo transducer and preamp that are designed for acoustic guitars--see earlier in the thread for details. The saddle is canted slightly off-perpendicular from the centerline...the E string is 32" nut-to-saddle, and the G string is 32 3/16". The harmonic matches the note at the 12th position on all strings, so intonation is as good as it needs to be. The saddle is also tilted back from perpendicular to the bass top, to provide more direct pressure onto the piezo. Again, more details earlier in the thread. Clarifying pics below.
