Martin OM Mikael Åkerfeldt
That's an interesting set of specs for an OM. The OM-35 was only made for a few years, and never really caught on, but I sure liked them. Evidently a Swedish metal guitarist I'd never heard of did too! I was very close to choosing the OM as the platform for my Custom Shop build last year, but opted instead for a 12-fret 0000. The OM I had already is a mahogany build, and there are things about that sound I just didn't want anything to compete with, so I went in a radically different direction, both sonically and visually.
Martin has done a pretty good job of 'keepin' it real' with most of these Artist Signature models. Some of them can be a little bit weird. I really like the three-piece back, as seen on Styles 35/36. Most interesting, (to me at least) and smart too, they used Guatemalan rosewood for the sides and back, and the center wedge is darker East Indian rosewood. It makes for a nice visual contrast, and allows for use of smaller pieces of valuable rosewood. Which was the original intent of Style 35. I don't think it was mentioned in the video, but to further geek-out on specs, that's an ebony 'pyramid' bridge... very cool vintage Martin touch.
Opinions vary on the VTS (torrefied) top, and the "Liquid Metal" pins. I have a couple guitars with torrefied tops, and it's definitely a different sound. I also have a few vintage guitars and no torrefied guitar ever quite sounds like ones that's truly aged and played for 80 years to my ears. They are mighty good. I didn't have it done to my recent Custom, and don't regret the decision. I also took a pass on the Liquid Metal pins. I think the main thing is to build them with good wood and keep the tolerances very tight. I think it's hard to mess up a good-sounding guitar with bridge pins or conversely, make a mediocre guitar better with them. The main thing is that they are fit correctly.
Anyway, that's a handsome guitar. And a very limited one. (only 74, according to Martin)
