Quote -  Newer all mahogany guitars are much heavier than old ones because the wood used now is much newer.  A Les Paul from the 1950s weighs a lot less than the ones made up to 2001.  After that, Gibson started drilling holes in 'em to keep the weight down.  They, naturally, call them "tone chambers".  We call 'em holes.  

Hahahahaha! Spot on mate!

(Actually, if you get a late 60s, or even worse, a 70s Paul, you might be unlucky. They can weigh a ton...)
