Converting passive bass to active with pre-amp...

    Hey bass folks,

    Since I'm having a hard time finding a medium-scale active bass within my budget, I'm thinking of buying a passive Aria Pro II TSB-650 and having a pre-amp installed to make the bass active...however, I know nothing about installing pre-amps, so I don't know if this is really a viable option...it's just hypothetical.

    Does this sound like a good or bad idea?
    Does anyone know how much it would cost to have a luthier or tech install a pre-amp, including the work to route out spaces for EQ pots?

    I'm going for a tone similar to Mike Gordon's, with a fat, round low end and clean, articulate highs. Any recommendations about what pre-amps I should be looking at?

    Thanks y'all :)

    Just get an external preamp like the Sadowsky and call it a day. Your signal chain will be exactly the same as if you had it put in the bass with much less hassle.

    I read somewhere that Mike keeps the EQ on his Modulus pretty flat and does almost all of his tone shaping from the rack.

    I agree that an external preamp would be easier. It would also give you more options to experiment without doing surgery. If the Sadowsky is too modern for you, you could flip it and try something else.

    Trying to chase Mike's tone – especially on a medium scale – with an internal preamp could eventually drive you absolutely nuts.

    To answer your question, contact Pat Wilkins. He just did an instrument for me for about $135 not including shipping.

    It's a perfectly reasonable mod, these days, as long as you aren't damaging any collector value in an instrument.
