I am selling my 6 string EMG pickups and preamp. The preamp is the BQS system and the pickups are the 45DC. The BQS is for EMG pickups only, this system features a pre-wired balance control (blend) and master volume with separate bass and treble pots along with the concentric mid-control (stacked). The 45DC (Dual Coil) employs parallel placed coils (ceramic loaded) to produce a deep low end, and yet maintain clarity. All of the DC Models are beefy, brilliant, and have more than enough output. The DC also uses the ultra low-noise preamp designed for the EMG- JV model. We recommend an 18 Volt supply for extended head room. This pickup uses a 45 Extended housing that is 4.5 inches (115mm). I have attached the stock pics but will have my pics posted tomorrow. Asking $175 for the entire system which comes with the pots.
