"Own it for life"
Can't beat the bottom end and surprisingly sweet up high too. The "boom" is one of the reasons Martins are unique. Bang on it like a rented mule and it just purrs and asks for more.
Bought mine in 1974 so it does'nt have a truss bar so the neck eventually tweaked. However I had it repaired (neck re-set, new pick guard, new frets, neck binding and saddle re-glue) for free! The action is actually better now than when I bought it. Own it for a lifetime and play it for life - you'll never pay a penny for repairs.
You get what you pay for. You can buy and sell lot's of guitars but when you buy a Martin you own an instrument for life. It's a classic.
They don't take them at the factory anymore but have a network of certified lutiers. In my case it took over 9 (yes 9) months to get it back.
You won't ever lose money buying one of these babies, But then again you will never sell it, so it really does'nt matter
The Wow Factor:
There are lots of high end custom axes out there, but you'll never be dised showing up with a Martin.
30 years and counting. "I'd rather fight than switch!"
