Martin Gibson, a Martin or a Gibson ( or a Hagstrom for that matter ) are just like any other reasonable guitar the world over. While some of them are very nice ( I have quite a few amongst the 30 or so currently in use)they can be good or bad. Martin bridges lift , just like Hagstrom bridges and need the same expertise to put right.
A luthier is a luthier, American or not, ( bearing in mind the european origin of most some of the greatest names around ), therefore your response to Richard Bridges comes across as less than enlightened.
As for your comments about pro musicians in America and the guitars they use....well it's just as well they don't hand out talent only when the name on the headstock is on the approved list.
