I guess tone is subjective... I've both chambered and non chambered and I prefer the non-chambered tone (agains thats just my opinion

). The chambered tone is great but I reckon it lacks some of the depth in tone I expect from wielding a Les Paul... I find it a little too bright... nudging into semi hollowbody country... but again thats just my opinion
What I don't agree with is not giving the customer the choice of either... I likes choice me
Then again its hardly the end of the world!
