The EMG-81TW humbucking pickup takes an EMG classic to a new level. The dual-mode design allows for maximum flexibility, with the original 81 providing all the crunch and aggressiveness it's famous for and an all new single-coil that features a fatter tone with plenty of punch and clarity. Either mode is accessed through a push/pull pot for versatility. Dual internal preamps, one tuned for single-coil mode and the other for dual-coil mode, give the 81TW two distinct sounds while delivering EMG's well known noise cancelling technology in both modes.
If you're using a Low-B String there's no sense in even trying a passive pickup. The 707TW Active Pickup delivers the clearest, fattest low end you've ever felt from a guitar pickup. The 707 is Alnico Loaded and the coils are summed separately keeping the DC resistance down and doubling the low end frequency response. Translated...that means the low frequency response is more natural sounding. Full, but not muddy. In addition, the dual-coil section has a wide aperture for plenty of string sampling. The resonance frequency of the dual-coil mode is 2300 Hz. In the single-coil mode, the pickup resonance switches up to 3900 Hz and operates in a "stack" mode truly resembling a single coil pickup, not a "tapped" humbucker. Still loaded with Alnico, the single coil sound is as pure as it comes. Dual internal preamps (one tuned for single-coil mode and the other for dual-coil mode) give the 707TW two distinct sounds for two pickups in one, while delivering EMG's well-known low-noise performance in both modes. Only an active pickup can deliver the big tone you'd expect from your 7-string.
