Well, not much of a tale really, more an example of my broken brain, but hey ho.
Got a new HB to scratch a fretless itch without having to save.
Changed strings (not because I don't like the HB strings, I do) but the replacements altered the set up.
So out came the Allen keys .
I suffered a major brain fart, tightening and tightening and tightening - convinced it would be right soon.
I shredded a couple of Allen keys and still I soldiered on.
I stopped, bewildered and exhausted. Took out my straight edge and, well, basically I had bent the neck way back the wrong way.
I don't need telling how dopey I am (but feel free of course) what I'm really here to say is this.
If you wonder whether the woods and components of HB basses are of a poor quality then think again. This neck ought not to have survived my heavy handed bodgery. Seriously. But it has gone back to a perfect relief, the truss rod still functions fine and it plays beautifully.
It was £144 new.
