Micro Alnico II by Gibson, the difference with the Classic 57 is that the normal model "Plus" has more winding, we find this microphone on a lot of bridge Les Paul Traditional, it has a very vintage and made very rock / bluesy side there is the limitation in the drive, or it will seek to push its limits .... it is very musical and smooth at the same time and at the same time it knows to show resentment .... it releases a lot of bass and top middle, it is a micro wax potted it has a side that can be suppressed too deaf to see some good but .... otherwise also tested for 57 + Classic uncovered (without metal cover) I find the model uncovered much drier and returned it ... except for the big muscular guy drive it will make High Gain draft, better take something like 500T or Duncan SH5 (ceramic) and for fans of micro Gibson Burstbucker there is 2 or 3 (spits more) ... without forgetting the Duncan Seth Lover and Antiquity who are really
PS: micro fetish Lenny Kravitz found throughout his Gibson (Flying V, Les Paul, SG ....) So for the fans ...
