Purely my own experience and anecdotes from others. I own a 98 H150 and a late 80s- early 90s 535. Both are incredible guitars and every person who has tried them comments on them, both will be on tour with me for a up coming project.
Ive heard a lot of people say about this era being sought after as the best was incredible and the worst just average. However I have also heard of the inconsistency’s of this era but I’d argue that’s down to the hand made nature.
Conversely, I’ve played several transition years heritages from across the range and they were all average at best and mediocre at worst. The shop I work for was a UK dealer at the time and could not shift them for this reason. Poor finishing such as bad fret work, poor woods, defects such as incorrect neck angle, electrical issues and just general poor QC when compared to the obvious comparatives.
I have heard since the new take over quality has vastly improved again and they are once again the sort after guitars they were.
