    Apologies for the numpty question...
    I have a Rumbler FS Ubass, bought 4-5 years ago and I have a question about the installed pickup, a shadow with built-in tuner & EQ. Is it likely to be a passive or active pickup? The fact that it's powered means I thought it was active, but it's that just for the tuner? However, I think it's a piezoelectric pickup, so passive, right?
    I'm asking in order to understand whether I should be using a pre-amp or not. So an answer to that and choice of DI box would be a bonus!
    Many thanks for your help.

    The output of the piezo pickups is so low that it requires a internal preamp.

    The only exception I’ve seen is Dave Wendler’s ElectroCoustic system. All passive piezo/magnetic system that sounds great.

    Doubtful they use something like that tho, AFAIK Dave has a patent on that system.

    It's an active pickup, you don't need an extra preamp.

    Piezos also require preamps because they sound terrible without them. Most amps are designed to receive a signal in the tens of thousands of ohms, which is what magnetic pickups put out. Piezo pickups send a signal in the millions of ohms. The preamp fixes the mismatch.
