Aguilar OBP-3 question

Discussion in 'Pickups & Electronics [BG]' started by Rafterman, Sep 16, 2008.

  1. my bass is in the shop getting the OBP-3 installed on my OceanTB75...the person that is installing it told me that the OBP-3 is only an EQ, and not a preamp...????

    She said that it would go with the bartolini mk-1 electronics in the bass...i thought the OBP-3 was a preamp...

    is there something i'm missing???

    OBP stands for On Board Pre-amp, that should be enough said.

    Though different people will have slightly different definitions of what a pre-amp is. Some will tell you a pre-amp has to be able to drive a power amp to qualify as apre-amp, well your OBP won't do that.

    I have the obp-3 on my 6 string bass, it is a very powerful eq/pre-amp/tomato/tomato.

    I hope she installs that PREAMP much better than she knows it.

    Depends on the PowerAmp. Any of my OBP-3's always pushed my Stewart World 1.6 PowerAmp just fine directly into it. Only really used it that way if I was testing changes to the bass strings, etc, but it would push the PowerAmp just fine.
