Hi Deadeye, I called a dozen guitar shops today, and nobody but one gentleman at used guitar shop knew the Daimaru guitar. He said that the company by the name of Daimaru was a trailblazer in the guitar manufacturing business that started in the early 1960s in Japan (it had nothing to do with the Daimaru department store apparently). A couple of people I talked to today also mentioned that many guitars were made and exported to North America and Europe for low prices by Japanese manufacturers from the late 60s to the 70s/80s. I read on the Internet that there were over 100 guitar manufacturers in Japan at the time, but their number is less than one tenth of it now.
According to the person previously mentioned, Daimaru factory was in Matsumoto in the central Japan, and they used Matsumoto wood (lumber) for their guitars. He said the company is long gone, and all the people who worked there are deceased (I’m not sure if the latter is true though). Daimaru was specialized in making classic guitars and pick guitars (f-holes) mainly, but when I told him that your Daimaru guitar is electric, he said perhaps the company consigned others for manufacturing electric guitars. That’s about all I was able to find out about Daimaru guitar. If I get more information, I will let you know. There might be some historic value with your guitar you just ran across.
As for BC Blues’ guitar in the interesting and mysterious story he shared with us, I was wondering if it is related to a guitar model called “Prestige” made by Ibanez (Japanese manufacturer). It looks like the “Ibanez” logo is usually found on the head of a recent model of Prestige guitar. Your guitar is vintage, so it may not be the same (it is also possible that it was made by a different manufacturer), but for your information, the following is a link to Ibanez website, on which some pictures of Prestige guitars can be found:
