Feature:
Nicely padded case was included with a handy zipper pocket on the side. The included strap is somewhat uncomfortable (the nylon webbing is a bit rough) but it does the job of supporting the Backpacker properly.

Quality:
For all its quirkiness, I really like this guitar. However, I do wish the finish was a bit more...generous. It feels just a bit rough, but I'm used to a fully-finished body. The neck is also (relatively) unfinished but is already gaining a patina just from being played. The wood itself is quite nice and the mechanics work well. The tuning stabilized in just a few weeks.

Value:
It's a Martin!

Desirability:
It travels well, which is what it's designed for. I have an excellent, concert-quality guitar but do NOT wish to do casual travel with it. Now I can leave my baby and home, safe and sound.

Sound:
The classical-style Backpacker doesn't have the rich sound of a quality standard classical instrument. However, it does have a delightful, almost lute-like tone, which was a very pleasant surprise to me since I primarily play Renaissance music. You need good nails to evoke the tone, but it's quite rewarding and noticeable even with a multi-instrument group.

Ease of Use:
Once the strap was properly adjusted, I found this to be a very comfortable, easy to play instrument. It's most definitely not similar to a normal guitar, but I adjusted quickly. I'm also impressed that additional bridges may be purchased if custom adjustments are desired.

Support:
I had an inquiry shortly after my guitar arrived, and contacted Martin directly. I received a useful, informative reply by email the next day. Well done!

Overall:
I think the Backpacker is perfect for its designed purpose. It's fun to play, gets interesting reactions, and has a very pleasing, if unexpected, voice.

Feature:
You will not believe how awkward to play this thing is. I bought to travel with and found the only position in which it is even remotely comfortable is if I play it laying down and its wedged between an elbow and my chest. There is no natural position for a guitar shaped like this. Also, it sounds like crap. I ended up buying a cheap Yamaha to take on the road and it sounds better anyway.

Quality:
Martin really should have put the "Sigma" stamp on this one. (Sigma is their "down market" brand name.)

Sound:
Imagine a hollow bat with strings on it. That's what it sounds like and that's about how comfortable it is to play. This guitar does a disservice to Martin (I'm a proud Martin guitar owner but this, this is a worthless POS).
