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 OBP3 is compatible with most major manufacturerΉs pickups, 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.
