    I have a -96 bubinga/wenge Corvette Standard. I'm planning to go active. MEC J set is the easy way, but I'm playing with an idea of having MEC J at the neck and TJ at the bridge. Any reason why this would be a bad idea? Routing for TJ is no problem. Am I right that I can have TJ single coil also?

    Youd be better off just keeping both singles and getting a 3 band pre to boost the mids at the bridge for that sound. The routing and extra pickup will be expensive.

    Routing will cost nothing as I can do it myself after making 20 or so basses. I'm not going to have an onboard pre. Passive MECs are too noisy at the moment, that's why I'm looking for actives.

    I think it is a great idea, the TJ alone will give you a thumb bass sound, and then the other combinations. How many strings?

    Four strings. Ihave found a used TJ locally for 30€, only the neck J is to be found, preferably used (cheaper) but if not, then I'll buy a new one.

    Some of the nicest Warwick basses have TJ in the bridge position, and there is no negative side effect for this mod, as TJ is really 2 J pickups put together, so make sure you add a 3 way switch (north coil south coil both coils) for versatility. Think well before routing what sound are you looking. One side of the TJ must be placed where the J is now, so you can place the other side to the bridge for a more aggressive Warwick growl, or to the neck for a Musicman-ish sound. Or ask the dolphin/ infinity etc owners how they have their pickup placed, but I would really do as described above, as the Corvette J pickups are placed in Jazz Bass sweet spots, I would not change this :)

    Extra coil closer to the bridge will give you a greater diversity of tones, the further you move to the neck the less evident the effect of switching coils becomes.

    If possible I'd switch 3 ways between series, parallel and the front single coil.

    Do consider an active pre, it will allow you to solo the TJ and still have a full sound, making this instrument truly a jack of all trades.

    I think it depends if he wants the bass to be more aggressive or more tamed than it is now. IIRC, corvette pups are placed in 70's Jbass position. So adding the coil to the neck will give you the 60's position too (sort of) if he wants a more mellow alternative. Coil to the bridge- yeah, that's a Warwick! I cannot comment how the series parrallel thing works in single coils, but I am thinking more like North + neck= Jbass, south + neck = streamerish, TJ soled= thumbish.
    Regarding the electronics, my personal prefference is passive controls. With the new pedals preamps etc, you can do whatever sound you like, better than the onboard EQ, which most of the time is not really THAT good. But for me passive tone opens a full range of other sounds imposible to get with active controls.

    I agree Florin regarding onboard tone controls. I have VT bass pedal and that has more than enough tone shaping possibilities. If I have onboard pre I'm turning the knobs all the time and can't decide what sound I'm after. I think I'm aiming for Warwick tone so TJ will be placed closer to the bridge.

    Hehe. My jazz model has everything you guys described. The two coils are indeed at 60's and 70's JB positions. Neck pu slanted like a jazzman/dolphin model. Passive because of the responsiveness.

    I think this will turn in to one fine Corvette++

    Go ahead already. A small note, normally you can't have series/parallel/single with the TJ, unless you want noise with the series mode (due to the individual shielding of pickups). I think Florin's advice makes sense, to place one of the coils in the current position. Although I always thought the right thing to do is to place the centerline of the TJ where the bridge J is.

    Now I just have to figure how to wire DPDT on-on-on- switch to neck coil-parallel-bridge coil. Can anybody help with switch schematic?

    Corvette pickups are spaced most like the 60s fender J bass, bridge pickup a little further. The katana has a 70s pickup spacing, wider gap between with closer bridge.

    I will look it up. Found a good source for wiring my own. I believe I have a bookmark on my computer at home.

    Any schematic that works for two pickups should work I think. They are really two pickups, with separate wires coming out.

    Do I need bridge ground with active MECs?

    Well, the modification itself was quite easy and the bass looks and plays great. TJ itself was a disappointment as it was advertised as an active pickup but it is passive. Well, now I have to find an active TJ to match the active neck J I have. At the moment the bass is passive with bridge/both/neck coil switch on TJ and blend between J and TJ. I gan get quite different sounds when blending J with TJ in different coil configurations.
