I would personally say (from experience) that my Sires are better quality than my MIM J, and comparable quality to my MIA Fender P. I've never had a Fender Japan to compare against, but I would expect it to be roughly equal or favor the Sire. All other things being equal (and they pretty much are, for me), the Sire preamp is a big winner for me, I like it better than the one in my MIA Fender.Hmm. Now I have to expand my wishlist...let me ask you this. People have said Sire can compete with any American, Mexican, or Japanese Fender. I have no knowledge. What do you think?
