I am your doctor of love!
Heritage Series (R8s & R9s, etc) are non-weight-relieved, and they too have the long-tenon neck joint.
Again - this whole argument is based on:
Long tenon necks sound better/hold up longer. There is no real evidence to suggest this at all. People bought short tenons for years before they even knew that Gibson changed and raved about the tone, and I have NEVER seen an LP with a neck broken at the body joint.
As for Chambering - also makes the assumption that heavier is better or whatever. Mahagony weight / density could vary quite a lot. If you listened to 10 LPs - would you pick a weight relieved on as "More comfortable and resonant / open sounding" or would you pick a solid one as being "more solid and vibrant"
You don't know if you KNEW ahead of time what you were playing.
All I'm seeing is excuses for spending more.
