    This is the photoshopped concept.

    Red Alder body, Macassar or Ziricote top. Matching headstock. Passive.
    Edit: smaller tone control knob applied.

    Stay tuned.

    Awesome concept and I am so in favor of the slanted J. It's perfect. It should be pretty aggressive and Warwick like due to the pickup positioning close to the bridge. Can you tell us a bit more about the controls? Also would you consider a high mass bridge?

    Yeah a high mass, string thru body bridge seems to be in place.
    The three switches which you usually find on the jaguar bass and guitar model only are for the twinjazz, choosing either or both coils and serial/parallel mode.
    The rear knob (small one) is passive tone, front two knobs vol/vol

    Pickups will be custom made, scatterwound. I am still working on output values I want to have.
    The bass will have a high gloss finish and most probably a maple neck with ebony fingerboard.

    Neck pickup moved towards neck a bit. Where it intersects with the E string is the normal jazzbass neck pu position.
    The front coil of the twinjazz is still at sixties bridge pickup position.
    Bubinga fretboard. Do you prefer the ebony or the bubinga fb? I am not sure yet...

    Weight would be an important factor for me. Is Bubinga heavier than Ebony? I think so.

    On average, Ebony weighs 65kg more per cubic meter then Bubinga (955kg vs 890kg).

    That looks super cool! I like some contrast so bubinga for my vote. It lets the dark body and headstock shine on their own, otherwise it’s a big dark blob to my eyes.

    That control plate is going to be annoying, nothing off the shelf will fit.

    Yep, leaning strongly towards the Bubinga fb.
    The control plate and pickups will be custom (hand)made.
    Bridge will be the bell brass ABM (already ordered) and the tuners hipshot, with a drop-D extender on the E string.

    I will take photos and report when we visit the woodshop (fijnhout amsterdam or arnhemse fijnhouthandel).

    Today the luthier asked me to join him in building the instrument so expect lots of updates right here.

    Something I wished I’d done on my mahogany p bass was to rout out the body for weight reduction. With your contrast top that is a perfect scenario for weight reduction. As long as the body is still the same stiffness weight won’t change the tone but it will be much more comfortable to play. I have to use a 3” padded strap and can only play one set, but I love it. I’ve been thinking about routing it out and putting a fancy top on it so I can use it more.

    I am not sure about that, the body of my bass will be Alder with just the flimsy Ziricote top. I think the weight will be pretty standard for a Jazz.
    Red alder weighs around 450kg per cubic meter, mahogany 600kg. Ziricote is 805kg. The extra weight will depend on how thick the top layer will be I guess.

    I will make calculations when I know how much of each type of wood will be used in the body and decide on 'tone chambers' (lol).

    I suppose it’s a personal thing, if I could build a 3lg normal looking bass I would. Damn back gives me grief but with regular stretching and yoga does alright. I should be more regular and it would likely give me no trouble but get too busy busy busy sometimes.

    You’re right with alder and maple neck it will be standard weight. If that’s good for you then don’t bother with weight reduction it won’t have a change on sound or look. I do love a thick top though, at least one inch.

    Wow. Pretty neat design.
    Conservative wood choice, though, which is not a flaw, but a surprise to me. :)
    Maple neck and Ebony FB will be very bight, In conjunction with the "Warwickesque" Twin Jazz close to the bridge.
    Given the body colour, I personnaly (but it's not my bass) would go for a White Oak, or something "light". Especially with the Matching Headstock.
    Or, and that would be a touch of madness, some twin colored Ebony.
    Walnut is also great for necks.

    It's a super cool build anyway,

    Well the idea behind it is it can do standard jazz bass tone (with the thinner strings sounding a bit fatter because of the slanted neck pickup).

    For this reason the front coil of the twinjazz pickup is exactly at sixties jazzbass bridge pickup position and the neck pickup is at the exact sixties neck pickup position where it crosses the E string.
    Also for this reason I chose Alder as my body wood and maple for my neck. Ash and other slightly harder woods then Alder will result in a more bright and compressed tone, which is not what I am looking for in this bass.

    Switching the mode on the twinjazz will result in a more middy, throaty 'jaco' like tone as it does on a Dolphin, which is also a thing I am after. I am hoping it will make the harmonics want to jump right off this bass.
    I have picked Bubinga as my fretboard wood by now, which is also the fretboard wood on my Ric v63 which is completely maple for the rest. It has a warm and lively tone with lots of depth and responsiveness.
    The topwood is just for shows and will be thinner then you see on some other basses because of the way a jazz body is rounded off at the edges.

    Combining all these things I have learned from other basses I own might work, it also might turn into something unexpected. There is only one way to find out

    One thing is for sure: This thing will be interesting, I am excited about this project!

    Bridge is heavy and solid. Looks like we have to go string-through-body with this though, or add a W style tailpiece =)

    You can also go the Ritter way.
    Or the Stradi way.
