Some players say that Modulus Quantum basses with EMG pups are harsh and bright. Yet many say the opposite. I got my Q4 yesterday and sound is more/equal to my liking than my other Bart-loaded Quantums. I did some reaserch and discovered that Modulus uses various EMG pups in the Quantum basses. The two most common ones are EMG-DC and EMG-CS. Per EMGINC.COM: EMG-DC: The DC dual coil features side-by-side coils that widen the magnetic aperture delivering a deep, full low end with slightly accentuated midrange EMG-CS: The CS dual coil adds a steel bar positioned above the ceramic magnets. This combo gives full, broad response with added warmth, while retaining a crisp, defined high end. EMG-P:The P style features two offset coils that give its sound more low end with brilliant highs I pulled the pups in my bass and they are EMG-CS. They are the quick-disconnect type as well--just unplug and change, no soldering. Just for fun, I'm going to order an EMG-P pup for the neck position. This is a P-Bass pup in the same housing as the DC and CS models. This might be old news to you Modulus Quantum diehards, but I just thought I'd share.
