That is a little shocking and know you are probably a little perplexed? Will require a little refining in that area. Some years ago when I had my 500/5 neck reset (with hide glue of course) the guitar luthier told me that it was a job better suited forma violin/ cello/ bass maker/ luthier for exactly the reasons mentioned and pictured. As you know Hofner redesigned their neck bass & pocket in the mid 90's. Some are still holding up since the 60's but only a matter of time. You might look up a local violin/ bass luthier for the slight refin. Good luck, at least it still has that lovely Hofner sound and feel!
