Also if you're interested in the wiring diagram to see how you'd hook this up:

I will also wire this u in a heavy duty aluminum enclosure (Hammond Manf. 1590BB-BK) as an external preamp with true bypass and an LED for $190

EMG 35DC, Volume pot, two screws, and connector for the pickup (no knobs): $50 *sold
EMG 35P4, Volume pot, two screws, and connector for the pickup (no knobs): $50

If you buy one of the pickups seperate, you'll need a tone pot for EMG pickups (if desired), a 9V clip, and a stereo jack that fits your bass to complete the install. (one of these: http://shop.donsmusiccity.com/p-1434-em ... -clip.aspx and you can get the vol/tone sets here: http://shop.donsmusiccity.com/c-182-pot ... -sets.aspx )
