I ordered a custom OM-28 last May that showed up yesterday! I'm thrilled! I wanted to blend vintage & modern designs and keep it plane Jane in appearance. The top is Adirondack spruce, and has Martin's "VTS" (vintage tone system, they bake the top to age it). The back & sides are Madagascar Rosewood, and the neck has the newish MLO high performance taper 1 3/4 nut 2 5/32 @ bridge. Martin used hide glue to construct. I've played her about 5 hours, and I am 100% a believer in the VTS thing. I have owned and played a madi/adi dread, and I'm very happy with the deep rumble and glassy sustain it gives the OMC. There's a decent chance this is my last guitar. She pops like thunder and shakes my body when I drive her with a pick, and she has a very sweet sustain that lasts forever when I gently use my fingers. Thank you Martin, you guys kick ass! Also, a very big thank you to Mark at Reno's music www.guitarhotline.com Mark is easy to deal with, and should be on everyone's short list when you go shopping for a guitar (I'm not affiliated, but I have bought & sold a few guitars thru Mark).
