Im looking into replacing my Sansamp RBI with (at this stage) either an Alembic F1-X or a Demeter VTBP201S. I play pop/rock and my bass is a MM SR5. The RBI is good but I find it acts like more like an effect than a preamp.. i.e. very couloured sound.. and I'm not a huge fan of the its sound with the RBI blend rolled back.. I use the DI out of the RBI at every gig. Just wondering how the DI outs of the Alembic and the Demeter sound in a live situation, any comments from FOH guys re. the tone/level? Also I read that phantom power can kill the Demeter.. is this also true of the Alembic pre? I read of an apparent lack of mid from the F1-X, could this be remedied by boosting the mids on my SR5 onboard EQ? Does the Demeter have any problem with delivering mids? Also just after any other comments on the difference between how these pres sound as I have not been able to find a great deal on the Demeter VTBP201S on TB.
