I've recently become a little interested in these guitars as a possible budget substitute for "name" guitars. Anybody with any info on how the acoustics by companies like Takamine, Yasuma, Yakami, Yamaha etc. compare to the guitars they are modeled after (especially Martin)? I'm specifically asking about the guitars from the 60s-80s that are obvious "copies", not divergent designs. I would think that since they generally used good solid woods and good craftsmanship they might be worth checking out. I also have an interest in Del Vecchio type guitars and apparently there are some Japanese copies of these as well.
