This is a Tesico-made full-acoustic guitar, sold overseas under the name Decca DMI 501 and domestically as Grace 2. Decca is the Decca record company, which had the Rolling Stones under contract. This is the American Decca, so I believe it was after the split. During the band boom of the time, the company imported and sold guitars from Japan with the concept of also selling guitars in their own record stores. It is unknown whether this particular guitar was exported to America in that way. It has a look that is somewhat reminiscent of Harmony guitars. It seems that it was sold domestically under the model name "Grace 2". After researching the manufacturer, it was written as Teisco everywhere, so I think it's almost certainly correct. The pickups are similar to those seen on Lake guitars. I don't know about the sharing of parts in that regard. Now, it's a thin-body full-acoustic guitar. There is a wooden piece, which could be called a sound post, wedged inside the body under the bridge, and thanks to that, the top doesn't sag. Regarding the neck, the rod has plenty of room, and there are no issues with fret buzz. There is some slight buzzing on the 1st string at the 3rd and 4th frets. The paint and headstock show damage, but there are no problems with use. The body paint, in particular, is covered in cracks and has a unique luster, giving it a considerable vintage feel. The pickups could be called gold foil, and they actually have some power, so they don't feel as weak as is often the case with bizarre guitars. They produce a clear sound in any position. The three control pots (2vol1tone), jack, and selector (i.e., everything except the pickups) have all been replaced, and they work well without any scratchiness or poor contact. Masking tape has been wrapped around the pickups to prevent resonance. The position mark at the 10th fret is sunken, and there is a small hole. There is no feeling of catching when playing, and there are no problems. There are some scratches on the fingerboard. The arm doesn't seem to be original, but it's small and doesn't get in the way, which is nice. It will be removed and included. The bridge was broken, so it has been replaced. The pitch is more accurate than the original. String height adjustment is also possible. It has a rather dry tone, which I think can be called a vintage tone in its own right. It sounds good.
