Onboard boost for big tone and precision control.

The Aguilar OBP-2 was designed to give bassists fat tone while being small enough to fit in tight spaces. Wired up with one 9V battery, it will fit into just about any instrument. With +/-18dB of boost and cut at 40Hz and +/- 16dB of treble boost and cut at 6.5kHz you can emphasize the frequencies you want to make your bass sound great in any mix. Add a second 9V for an extra 6dB boost.

  • Low-noise, discrete FET input stage
  • +/-18dB bass at 40Hz
  • +/- 16dB treble at 6.5kHz
  • Separate treble and bass knobs

Order your OBP-2SK today to thicken up your bass tone.

    Comments about Aguilar OBP-2TK On Board Bass Preamp:

    I was expecting more out of Aguilar. This may be a great buy for others but for me this is one of the worts products to upgrade my bass with. I would of rather kept the original Preamp my SUB Bass came with stock if I wanted a real boost on the Treble and Bass.
