Sadowsky Outboard as only preamp?

    Has anyone used the outboard DI/Preamp pedal with a passive bass as the only link between the bass and the poweramp? Very interested in how it sounds and if it's an ok idea. I have outboard compression and EQ so it doesn't bother me that the settings on the Sad are limited.

    OPINIONS NOW!!!!!!!!!

    I think you will be disappointed. I haven't tried this with mine, but I have with my SABDDI. I am willing to guess that the Sadowsky will have the same result. Neither send a signal hot enough to drive a power amp sufficiently. They are not built for such purposes, and you will get very little volume and disappointing tone out of your power amp/cab.

    I tried my SABDDI with a Stewart 2.1 mono bridged into an Eden 410xlt, and still wasn't getting enough volume for modest playing levels.

    You apparently aren't aware that you can just de-solder one resister in the SABDDI to get full power to drive a power amp all by itself . . .

    Output voltage of the Sadowsky is different in any event. Anybody actually try it?

    Eric -

    Please give me details. I must do this now. It is my mission.
    Thank you.

    Hmmm. That means that you could install a switch in your Sadowsky/Aguilar/etc. outboard (resistor in-line or not) and have it function as either an outboard or a stand-alone pre amp...or did I miss something? So it could be your spare pre amp if the rack pre amp went south?
  6. I haven't used the Sadowski model but I have used the Aguilar DB924 which are similar from what I understand. The output level wasn't strong enough on its own, but the addition of a rack mount EQ with an output level was all I needed to get the required signal boost.

    It sounded good to me, if not a little too dry. That is only my preference, not a judgement on the sound quality. Now I use a Sansamp ADI with the same configuration with great results.

    I say go for it. Just be sure you use a signal boosting device between the Sadowski and the power amp.

    In the BDDI, there is a mark on each side of one resistor that looks like this: < > Just desolder and remove that, and it will deliver the increased output.

    There was a complete thread on this about a year ago here at Talkbass. Search for it, and be enlightened . . . ;)

  9. I'm sure this was probably addressed in the previous thread...but I'm lazy. : Will this not decrease your battery life? Seems like to push that kind of line level, is gonna need a lot of juice.
  10. Oh...ok, I have the old 'belt model'...forget my last post.
