Mendel P is here! It's not ready to be shown to the public because: The notes at the 7th fret and beyond start choking out. Only when it gets to the 12th fret does it choke out completely. To put it simply, the frets are touching the strings too much where no string vibration can happen. Not sure what's wrong. I feel like I do need to tilt the neck upwards just a little bit. The bass came in parts; neck and body separately packaged in the same box. I put it together before doing any setup on it, put on some strings, and played for five minutes. It was fine; action was a bit high but no choking on anywhere on the fretboard. Only after I did a pickup swap did it start happening. Not sure what's happening. I made sure the neck and body joints were tightly clamped together before screwing on the mounting screws. Any thoughts/suggestions?
