The OBP-3 is Aguilar's most flexible onboard preamp design, providing +/-18dB of cut and boost at 40Hz, +/- 16dB of cut and boost at either 400Hz or 800Hz and +/- 16dB of treble cut and boost at 6.5 kHz. The OBP-3 has multiple wiring options, and can be wired with either a push/pull pot, mini-toggle or internal dip-switch for midrange frequency selection.

Aguilar preamps have high headroom, low distortion and reproduce the full dynamic range of your instrument. The OBP-3 is the "Aguilar Sound" in an affordable, easy to install package. A great upgrade for any bass!

"I own 30 basses and I have the OBP-3 in about 20 of them. That’s because the other ones are passive! LOL. Low end is big but not muddy. Mids are fat and not nasally. The Treble is perfect. Love this preamp!"
