This beautiful Martin Custom Shop 28-style features an OM Auditorium Body that strikes the perfect balance between size and projection. The OM series, originally introduced in the 1920s, was designed to offer a versatile instrument suitable for both fingerstyle and flatpicking techniques, and this guitar exemplifies why OM Martin's are so beloved, offering scalloped x-bracing under its hood to help its natural projection.

This model, being a 28-style, features a body made with an Adi spruce top, and East Indian rosewood back and sides: two woods with a stark contrast in color that work surprisingly well together, visually, and that are loved by Martin fans as a common pairing as tonewoods. Purfling runs the length of the back of the guitar, separating its two bookmatched halves. 

The neck, carved from select hardwood, features Modified Low Oval Profile with Martin's notoriously comfortable High-Performance taper. The fingerboard, which meets joins the body at its 14th fret, sports a fingerboard made of ebony with a 16-inch radius, topped with 20 total frets and Long Diamond and Square inlays made of abalone. 

Finished in a stunning natural gloss, the decision to add aging toner to the top imparts a subtle patina to the wood, allowing the grains of both Adi spruce and East Indian rosewood to shine fully with no interruption. 

In the hardware department, this beauty features a bridge made of ebony and Grover nickel tuning machines, and comes with an included hard shell case. 

Most new Martin Guitars ship with the original endpin not installed, if you'd like us to install one for you before shipping, please let us know and we'd be happy to.

Great little notebook
Style: COVER
I love these little notebooks. I have a case that they fit in just fine, along with a pencil. I use them primarily for my ham radio hobby for when I go to a park and need to record the contacts that I have made for the log.

Nice quality but could be better for the price.
Style: COVER
So nice quality but strange dimensions. There is no way to fold a standard 8.5x11" sheet of computer paper to fit neatly in this. So if you want to print out your own documents to take with you in this, this isn't ideal. Has 2 internal pen slots and one on the outside. Has two business card slots but I wish it had more.

Pen Holder is Very Narrow
Style: COVER
Overall this item is effective for holding a Rite in the Rain 4.625" x 7" spiral side-bound notebook. There is no zipper on this so it does not seal. It has slots for a few cards and folded or smaller items can be tucked behind the notebook in the pockets that hold the covers. I haven't used it in the rain enough yet to know if those papers I have tucked in will stay dry. The description says a cell phone could be stored in those pockets as well. I haven't tried this, but my cell phone with a cover wouldn't fit. If you have a thin cell phone it might work, but I prefer to put both covers slid into the pockets so the notebook stays open easier when using it. The outer elastic closure is tight enough without being too tight. However, the pen holders are quite tight and small. They likely work well to hold in the Rite in the Rain pen that is narrow and smooth and possibly a narrow and smooth mechanical pencil, but they are too tight for my side click mechanical pencil. I could barely slide it in and when I tried to pull it out, the top half pulled off the bottom half of the pencil. It would also be a struggle to put larger pens in and out, but the elastic might stretch to fit those that are smooth over time. Despite not being able to use the loops for my preferred pencil, I chose to keep it.

Just what I was wanting
Style: KIT
Ordered to use a a gym notebook to track my progress. It’s holding up well being exposed to being shoved in a cramped gym bag repeatedly over the last 2 months. Sweat and water hasn’t hurt it and the cover seems to be holding up well. Still looks practically brand new.
