DESCRIPTION

Give your bass some ballz with one of the most powerful preamps available. With 16-18dB of boost/cut available, the Aguilar OBP3 can really add (or cut) a lot to any and all of the three frequency bands. Carefully chosen switchable mid frequencies (400 & 800Hz) allow you to be heard amongst your bandmates.

Our Aguilar OBP3 Bass Preamp Custom Kits include the components that you need to install this in your bass.

This kit includes:

  • Aguilar OBP-3 module
  • Potentiometers and switches (if applicable)
  • Stereo Jack
  • 2 Battery Clips

This kit does NOT include:

  • Pickups
  • Knobs

Black round switches included with configurations requiring switches.

Prewired OBP-3 Bass Preamps are wired for 9V operation.

We offer the custom kits kits in both pre-wired and non-prewired. These customs kits go a step further than the standard Aguilar kits and provide more of the components needed. Pre-wiring delivers you a preamp that is almost to the finish line, just the final couple connections and installation into the bass is all you need to do.

Aguilar OBP-3 preamp pre-wired

The OBP-3 was installed in my Ibanez SR1800E. The preamp that came with the Ibanez was effective, however it failed. Along came the OBP-3 to save the day. After installing it I didn’t expect much based on my experience with the Ibanez preamp. I plugged in, set the bass to passive, played a few notes. Sounds nice. Then I played a single note and while it rang out I switched it to activate….HOLY WOW!!! This preamp blew me away! The OBP-3 is only wired for 9-volt and it has more oomph than the Ibanez. I would go as far as to say it has twice as much output as the factory preamp. I can’t imagine what would happen with 18-volts running through it. The power is amazing, the tone is incredible. I ordered it pre-wired and the pots that are included are great. Needless to say, I love this preamp and would not hesitate to buy another one if the need arises! Fat Bass Tone was great to work with. The gentleman I spoke with gladly answered all my questions. They shipped exactly when they said they would and if not for the Post office, I would have received it quickly. But that was my fault for picking them instead of another carrier. Thanks Aguilar and Fat Bass Tone!
