Since posting this blog piece in November 2012 the eBay value of these guitars has rocketed from under £100 last year to £500 as of May 2013. Please bare in mind every single one of these Yasuma models I have seen are under-set with very high action. They also have a two-ply laminated top not a solid top. If you plan on spending hundreds of pounds on one of these models please ensure you play it first before parting with your money.
In the 1970s Japanese manufacturers began to get more serious with companies even attempting to pass themselves off as American brands such as Martin. These were high-quality and looked too close for comfort to the real thing. The Yasuma Musical Instrument Company was one of many who fell foul of US litigation and were ultimately put out of business.
This 70s Yasuma is essentially a Martin D28 copy. The sound this dreadnought produces is unreal. The guitar is noticeably light and has huge amounts of crisp bass response. These guitars are finished in nitro-cellulose (sprayed over the scratch plate). The familiar Martin dot markers were probably the last straw for US lawyers. It did however require a lot of work to get it playable. The string action was 10mm from the fretboard due to the height of the bone saddle. The machined work inside the closed tuners looks like it was precision built by NASA. Yasumas are a rare gem, but if you are buying one online without trying it first don’t expect it to play out of the box, they do need setting up.
