| Sennheiser md421 vs md421 mkII ??
I am going to look at used black body Senn MD421 that the seller says was made in the '80's. I have an older gray tuchel plug European model that I like, that sounds different from the newer models.
What is the sonic difference between the older 421's and the newer MkII's? Is there a physical difference that would delineate an older black body 421 from the MkII's? |
