Hi, long time no speak, good to hear your still about. I'm off for a ruby with the wife to celebrate today being my birthday so hopefully in good spirits later.
On to your Q.
I don't read either these days mainly because they are full of adds and rubbish articles.
On the Mahogany thing, which species of Mahogany are they talking about? Some are in scarcer supply than Braz Rosewood, others are only just being tried and in plentiful supply. Many of the Mahoganies out there aren't true Mahoganies in any case. I'm not about to worry any time soon but I don't buy as much timber as Gibson.
Beware of Gibsons marketing speak it is among the most self serving in the industry. Don't forget only a year ago they had reinvented the guitar and we would all be playing self tuning guitars in the coming days.
Hows you bro by the way? Haven't seen him round much lately either.
