I can answer those questions.
Cold Sweat and Miracle Man,
which pickup has the less bass?
All things being equal, using a clean setting, the
Cold Sweat has more low bass and lower midrange. Overdriven, the Cold Sweat has even more bass, lower midrange, and midrange, with a slight rolloff in the high frequencies. With the Miracle Man, there is a rolloff with the hig freqs as well as the upper midrange.
which has the less output?
They both have the same perceived output, to my ears. However, I classified the Cold Sweat as being more 'driving', while I think that the Miracle Man is 'tighter'.
and which one has the most mid range?
Both pups have virtually the same amount of midrange push in the neck position. Subjectively speaking, the Cold Sweat has more air, upper frequency push, and harmonic detail in the neck position.
So, to sum up:
In the neck position --
Less bass = Miracle Man
Less output = n/a
More midrange = n/a
Hope that helps!
