I think they are the same... this one hasn't got the date on either... but you can see the "smudge" where it was, this is one of the amps on the right with the small stamp.
Maybe it is possible that there are to different stamping methods, and the smaller of the two wipes off easily??
I'm currently scanning another angle of my amps...
I'm hoping that my two amps just have been dated with different style stamps.... because even under a magnifying glass they are identical. Hopefully they are both legit.
As for my amps and yours..... God knows! we need more experienced input bro. should they say pakistan or Kurachi???? maybe they are both legit.... Help!!
Karachi is a town in Pakistan, I think those amps are more likely to be true. Pakistan LTD sounds strange. Just like a company would name it's brand after a country... Like UK ltd ?? ehhh..
But what do I know? Nothin I never used any of them and will never do it unless all gear in the world dissapear exept them
