Aguilar OBP3 Preamp

We associate the Aguilar DCB pickups to their own Aguilar OBP3 preamp. The illustration shows you where to find which control knob on our Napoleon Bass.

Please note the two available switches on the bass:

  1. The lowest one is the active/passive switch
  2. Next to the medium booster, a 400/800Hz medium frequency selector-switch
