quick (really) box Q

[aziltz]

is what is called at 125B the same as the hammond 1590B? but 125B is a taiwanese version?

[markr04]

Yes.

Not exactly,
If your talking about the box that Small Bear calls "Box - Taiwanese 125B-Size", than no.
The 125B is longer taller and wider. 
Its closest Hammond equivalent is the 1590N1  (I think).

If your talking about the box that Small Bear calls "Box - Taiwanese 'B' Size ", than yes. Its the same.
