The Aguilar OBP-3 was built from the ground up to be the ultimate source of full-bodied tone, transparency, and versatility for your bass.

Three bands of boost/cut and a selectable midrange frequency provides flexibility to dial in just the right tone. The treble control delivers up to 16dB of boost/cut at 6.5Hz and captures the dynamic of a "Passive Tone Control" when rolled off. The powerful midrange control offers user selectable frequencies of 400 or 800Hz, each with a full 16dB boost/cut capability. The midrange retains constant bandwidth in any setting so there is no "muddy" frequency overlap. The bass control features a boost/cut of up to 18dB at 40Hz, adding Aguilar's signature thickness to any instrument.

The Aguilar OBP-3 is compatible with most major manufacturer’s pickups both active such as EMG®, Warwick® MEC, and passive as we build them in house and impedance match the controls, and its small size makes it an easy retrofit in almost any bass. Combining high headroom and low noise, the OBP-3 is unmatched in providing tonal flexibility while retaining the true character of any bass!

Tonally these preamps are aggressive, clear, transparent and have emphasis with the low and low midrange being warm, and with the top end 'presence' like. These preamps do not have gain control onboard.

Use of 9v or 18v power is possible as we build the prewires in house to suit your power requirements. 18v grants an additional 6dB of headroom.

I am really please with this Agular preamp combined with Dalano pickups on a Mike Lull V5 bass that was passive until now. The bass is Ash with a figured maple neck & sounds like Marcus Miller's bass. I've used a lot of preamps and pickups but the combination is by far the best sounding !!!!!!
