At that point in the early 80s Japanese guitars were just coming out of that "copies" stage, there were lots of original designs and good ones too. Then, for better or worse, just after that the superstrat thing took off and everyone started building variations of the same thing - HSS, locking trem, pointy headstock, yadda yadda.
I suppose there was still snobbery about Japanese guitars, although everyone I knew had them. I just happened to get a good deal on the Hamer, I'd have been very happy buying Japanese otherwise.
Thinking about it, even at the start of the Superstrat Epoch they were all using American guitars, Jacksons and Kramers. Then Jems/RGs came along and Japanese guitars were taken seriously. Then we all started getting snooty about Korean guitars. :roll:
