The EMG-DMSK Dual Mode Switch Kit allows you to simulate a single coil sound with any EMG humbucker pickup. It utilizes a capacitor in series with the pickup output to naturally roll-off the low frequencies. For even greater flexibility, the kit includes three individual capacitors that allow you to tailor the roll-off to your tastes. Activated with the single toggle mini-switch, the DMSK can be used much like a humbucking coil-tap without the hum associated with traditional coil-splitting. The DMSK also preserves the low impedance output of the pickup.
