This is one of those orphan show up at the door in a basket with a note kinda guitars. It is badged Sonata but is definitely Harmony built. Has a S-43 date stamp and one of those funky wood tailpieces that Harmony used when their source of metal dried up. The guitar definitely has its issues but it did not take a lot of work to put it on the road. It is a surprisingly good playing guitar. All birch but the top has about the best graining job I have ever seen. It even had me fooled at first look. While the last thing I need is another one of these el cheapo chic sweeties, I figure the Kluson bent tab tuners alone are worth the price of admission on this one.
