Okay, call me a radical.
There are reasons why adjustable truss rods were invented. I've never once heard a discussion on how a T-Bar or Ebony truss rod positively impacts the tone of a guitar, but I do know that you cannot adjust neck relief, allowing easier play and more enjoyment of the instrument, with this outdated technology. So why in the world would you spend the amount of money Martin is asking for a guitar that is guaranteed to have issues a few years down the road?
I understand the love of Martin tone, and I understand the pursuit of authentic (original) pre-war models and the magic some of them possess. But there is no correlation that I can surmise between magic prewar acoustic tone and the inability to compensate for poor intonation or unplayable fretboard action. Especially on a new or somewhat new guitar.
Someone, please, educate me.
