The MK4CBC pickup is an MK Soapbar shaped bass pickup for the bridge position. It is 4.24" / 107.57mm long and 1.33" / 33.66mm wide. The dual coil design features powerful lows and low-mids, with bright treble.
The Classic Bass series bass pickups are passive designs featuring an extended and more resonant frequency range. They have far more air and definition at the top without sacrificing lows and low mids. They are cast in epoxy to remove unwanted feedback and micro-phonics.
