Originally fitted to my Les Paul Custom Orville By Gibson (other feature Classic 57) HB and HB-L-R undoubtedly regain Gibson grain, but with one side less "muddy" than a lot of microphones of the brand. A significant feature is the ability to split these microphones, originally equipped with the 4 + son mass, which is not always the case with Gibson (link the two coils is in the microwave).
More versatile than the classic 57 more medium because it is also a bit (a bit ...) less interesting blues / jazz.
Otherwise, it's very very good ... A test anyway, the grain is typed vintage.
