Inside the EMG 40TWX are two independent pickups: a single coil and a humbucker, with the X Series preamp for increased dynamic response and clarity. The single-coil mode is EMG's JCSX pickup built with ceramic and steel magnets for a rich, warm tone. The humbucker mode is EMG's popular CSX (ceramic steel) dual-coil for a big, aggressive sound with a pronounced mid-range.

The X series preamp gives the pickup a more dynamic range along with increased headroom while keeping the more traditional string-to-string balance. X series pickups also come with an Active Tone Control (VLPF) designed to roll-off (attenuate) high frequencies, similar to a typical passive tone control. The result is a noiseless single coil guitar pickup with a classic EMG sound that bridges the gap between active and passive.

When using two of TWX Pickups in the same instrument it is not recommended that EMG's BT or BQ Systems be used. Each pickup requires a push/pull pot for switching from single coil to humbucker, so the balance control included with the system can't be installed. If you want to use the balance control, consider switching single/dual coil outputs with a DPDT toggle switch(s) instead.
