My name is Jerry and I'm a nut. Self-supporting, but I have been on the dole too, as well...yeah it seems a bit of wood behind the nut, clamped n glued would do the trick...I personally like a big zero fret unless I'm going for higher…"
Many thanks for your comments, Jerry. The second output comes from a piezo pickup that is not visible and is attached to the plywood face under the central bracing bar. The preamp is always in circuit to the first output and its level can be adjusted pretty easily with the volume control. The idea was to have options for the different pickup responses of the electret mic and the piezo - or even combine them, although I've not tried this. Enjoyed your photos - some good looking guitars there!
