The OBP-2 was designed to give bassists fat tone while being small enought fit into tight control cavities. Wire this preamp with one 9 volt battery and it will fit into just about any instrument. With +/-18dB of bass boost and cut at 40Hz and +/- 16dB of treble boost and cut at 6.5 kHz you have can emphasize just the right frequencies to make your bass sound great in any mix.

The Aguilar OBP2 is compatible with most major manufacturer™s pickups, and its small size makes it an easy retrofit in almost any bass. Combining high headroom and low noise, the OBP-2 is unmatched in providing tonal flexibility while retaining the true character of any bass!

No modification is required for use with Active pickups such as EMG®, Warwick® MEC and other active pickups as we build the pre-wires in house and impedance match the controls for the pickups chosen whether active or passive.

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.

Aguilar OBP-2
By Daniel Bonin
Sounds great on my Jazz bass. Even with no mid control I still get a very punchy and well define sound.

Perfect upgrade
By Mark
This inexpensive "road" bass is now the envy of all my pro bass player friends. Everyone now wants to borrow this miniature bass I built to throw in over head compartments on airplanes. Who knew? Other reviews mentioned something about the frequency at which the treble is set being a little abrasive. With two pickups I am usually set close to center in balance with the bass slightly boosted and the treble slightly cut. The sound right there is amazing so that 6.5K issue really isn't an issue.
