UTILIZATION

The bass drum can Dreadnought parraître cumbersome, but I find myself very comfortable. a crossed out it's more complicated than a electric, but the sound that comes out is truly amazing.
the handle is very nice, access to acute is necessarily difficult it beyond the 17th box, but if you need more, we take a cutaway.

SOUNDS

I was amazed by this guitar. after trying several guitars, and even higher for models martin, I came back to this guitar and not a budget issue.
Both opinion, I agree that all dx-1 does not sound like that, I tried two, was really a classic for me, I did not really like, then I tried another elsewhere, and I fell in love with the warm sound from the first agreement. a warm and round, this guitar is perfect for the folk song to Jack Johnson or Ben Harper. the highs are really good.
if you want a warm sound, I urge you to try this guitar.
a small flat on the "reasonable", I found a lack of scale due to the roughness of rope, and pull the hammer of not apparent more than that in the game
but I really fell in love with this sound, you have to try, it is very personal.

OVERALL OPINION

I pretty much said everything, I had a crush while trying this guitar. we find the characteristic sound of martins that I have not found on other guitars.
This entry is for me far more expensive models. to buy eyes closed.
I have not had much opportunity to make use of the Fishman preamp, but it seems well made (the fishman is at the same time, the reference.)
