    I have an extra Aguilar OBP-1 preamp for sale. The OBP-1 will give you expanded tonal range, adding real lows to your bottom and snap to your high end. Even with the tone controls set flat, your pickups will be buffered and keep their clarity even with a long cable run. Also, this preamp has a "big" sound. Does not compress the signal like other preamps!

    The preamp will come pre-wired for active pickups (such as EMG or MEC Golds) and will include a wiring diagram and a 9v battery clip. This preamp can easily be modified for use with passive pickups as well by just swapping the 2 volume pots out for a different value (that being whatever volume or vol/blend pots are currently in your bass). The pre-wired 4-knob configuration is: Vol-Vol-Bass-Treble. An OBP-1 preamp pre-wired as such if ordered new from bestbassgear.com will run you $173. I’m asking $99 $89 including shipping with payment via PayPal. Please PM me with interest or questions. Thanks for looking!

    Maximum amount of boost: 18db, occurring at 40 Hz for the bass, and 4kHz for the treble
    Output impedance: 600 ohm
