Selling a set of Aguilar DCB soapbar humbuckers that are in excellent condition, as well as an Aguilar OBP-3 preamp with a push pull selector for the mid frequency knob and a stacked bass & treble pot for a 4 knob system. These came out of a Spector 5 string that I recently acquired and put the stock EMG pickups and 18v Haz preamp back in to be consistent with these other 3 Spector basses I have with active EMG pickups. These DCB pickups are a great sounding, high output passive soapbar pickup with great definition and depth. Here are the details on these particular pickups - these are a direct replacement for the EMG 40 series pickups: Aguilar DCB Pickups are dual ceramic bar magnet pickups that provide a dynamic and responsive attack that works for all playing styles. The Aguilar DCB Pickups produce well developed overtones and singing sustain in the body and decay of notes. The uniform magnetic field of the Aguilar DCB Pickups bar magnets allow for each note to have an accurate dynamic response and capture more harmonic content. The DCB Pickups capture all information from the string as it vibrates back and forth. Aguilar uses a proprietary design that takes these benefits to a new level that will bring out the best qualities of any electric bass. Aguilar DCB Bass Pickups sound great installed in a passive bass or with an onboard preamp.
