We make special models for different markets. Japan was the first market to have a high acceptance of the guitars, largely contributed to by Katsumi Watanabe's use of a gorgeous flame schedua Series I guitar.
Shinseido is our current importer in Japan. They have specified the Retro models with many features of our early instruments (channel bridge, thicker body, 70's template). When I was in Japan a couple of years ago, I made measurements and recorded the specs for these modles.
Here's one of the guitars we made after my visit:
This style doesn't even have a truss rod cover it's so retro.
