The guitars that I have bought from this seller seem to be all from Mike's Music. (Wouldn't you just know it.) This is the 3rd Tokai Strat that I've gotten, and they were all beautiful instruments. The first was Korean, with some minor cosmetic problems, and the second 2 are supposedly Japanese manufacture, and in perfect condition. I don't understand the reason behind the various seller names involved, but can't complain about product, shipping time, or price. Maybe the volume of business they do affords the chance to obtain prototypes and limited run issues that are not avalible elsewhere. Anyway, the examples that I have do not have any obvious serial numbers, but sure are wonderful guitars. Seems like it would be alot of trouble to "create" unusual Tokais with matching cardboard shipping boxes and all, for a few hundred dollars.
