Yeah, I have considered a replacement nut, but I'm not thinking too much about that now. My big decision now is how I want to do the Flexcore preamp. Two of the five knobs are for volume (push/pull active/passive) and pickup blend. For the other three, I can either do bass, treble, and stacked low mids/high mids, or stacked bass/treble and separate high and low mids.
