OBP-3TK

Aguilar OBP-3 Bass Preamp Standard Kits

The OBP-3 is Aguilar’s most flexible onboard preamp design. 

  • The OBP-3 preamp provides +/-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 OR mini-toggle for midrange frequency selection.

    Black round switches included with configurations requiring switches.

    The OBP-3 Standard Kits include the preamp module and EQ pots (and switch when specified) only.  To find a more complete kit, with the option to have it prewired, check out the OBP-3 Bass Preamp Custom Kits.
