The MC Series Multi-Coil Pickups have two coils per string. In a 4 string pickup there are 8 poles, 2 per string, where each pair of coils is wired in series as a humbucker. In other words each string has its own dual coil humbucking pickup.
The individual outputs from each string feed an ACG IB1 interface board, which mixes them electronically. The multiple coils and electronic mixing reduces the interaction between the strings coil signals, since there is no cross-feeding between string signals as with traditional pickups, where the same magnet systems and coils are used for all strings.
This leads to improved dynamics and far greater clarity over the entire range of the bass.
There are two versions of the IB1 interface board. The IB1f version has a flat audio response where the natural response of the pickup is left intact and would normally be paired with a neck pickup. The IB1r version has interactive pickup resonance in the upper presence region which gives rise to greater clarity, particularly with fingers style. The IB1r would normally be paired with the bridge pickup.
We believe that our MC Series pickups offer you the most sonic versatility and clarity possible, in conjunction with our ACG EQ03 every possible subtlety and nuance is present and there to be played with.
