Radial JDI or J48?

    I have two passive basses, but I use one of them with a SV-Pre most of the time. Do I need a passive or active DI?

    Not a rule but a guide line.
    Active bass....passive di
    Passive bass.... active di
    Both are good choices. My j48 is a freaking tank

    Nothing set in stone but....it's a start.

    ....and I use the JDI with passive and active basses without any issues.
    The deciding factor for me was not having to worry about phantom power.
    Both are good choices. My JDI is built like a freaking tank. :)

    I’ve used the JDI with both passive and active basses. It’s a great DI, and yes, it’s built like a freakin tank. Never used the J48, but I’d assume it’s equally as great.

    I like the way the JDI sounds running my pedals in front of it, works that way with either my active preamp EBMM or my passive Peavey T45.

    I don't get why people are worried about phantom power .....if a DI is used.....there is a mixer.... therefore....48v.... always.

    Phantom power, just one more thing that can go wrong ... passive DI = simplicity

    Y’know how I know you’ve never done a gig where the XLR cable was bad/miswired?

    This. I always have a JDI in the gigbag ... just in case. And it's bailed me out a couple of times.

    Use another cable. Bad xlr won't be any better with a passive di

    Another quick question: why are they so expensive in relation to say the sansamp? You’d think they’d be much less expensive

    The 'J' in the name is a Jensen (Jenson?) transformer; they're expensive.

    I like the Countryman Type 85 for a simple active DI. It runs on phantom, but also has a 9V (that gets around 400 hrs of use) that will take over power if phantom is not there.
    Just change it like once a year, and you will never have an issue powering your DI box.

    I think if I was using a preamp the majority of the time (like the OP and his SV-Pre) I would go with the passive JDI.

    Here's mine.
    It has never let me down.
    Sounds great with both my passive and active basses. Doesn't need phantom power.
    It is built like a big ol' freakin' rat stompin' guitar crushin' tank.

    Anybody compare the PZ DI to these? The variable hpf and push button lpf onboard is so tempting.

    Powered only by 48v phantom power though. Any idea how to keep one always on for a pedalboard?

    Simply can not go wrong with a JDI in your arsenal.

    Now I'm thinking people don't "get" the 48v thing......
    They seem to think of it as a hassle or negative feature. Every mixer on the planet (99.9999999%)
    has phantom power.....so what's the problem.....????

    Get a dedicated filter pedal.

    The J48 doesn't have a Jensen transformer.

    The active bass with passive DI, and passive bass with active DI, is a good suggestion. However, if an effects pedal is on, it’s likely sending a low impedance signal from the pedal to the DI. I have a compressor pedal always on. So no matter what bass I’m using, the comp is sending a low impedance signal. I have a JDI, which I really like, but I’m typically either using my REDDI or a Mesa Subway DI (at church).
