    So basically you ask him to make a bass, just not assemble it? :p

    Thanks again for the kind words! :)

    Well, this trafo thing is a bit of a trade-off, and a lot of work.
    You get voltage gain, which is interpreted as a stronger signal by the amps. But you have to find an iron for it that is small enough to fit in a bass yet big enough to wind 2-3000 turns; also, it has to have even frequency range. Now, this doesn't, it starts getting wacky at the highs, but fortunately those highs are in the >10kHz range :smug: A lot of irons behave badly in the lower freqs, too, which is especially bad in this use. Also, it adds some weight; and it needs good shielding.

    Corrections from my Dad:
    this is a "Permalloy M"-type iron in this one.
    Hypersil also works nicely, but is bigger.
    Going with the "if it sounds good, it is good" mantra, we kept it. :) The output was very weak otherwise.

    You must be dedicated to the passive thing... I would have just gotten a Bartolini buffer pre.

    Yeah, we also built an buffer pre, but I liked this design better.
    C'mon, no batteries - no worries :)
    Going with an aftermarket pre would've been expensive here - and everyone can do that :smug: :p

    haha.. PERHAPS...

    i'd be making the body

    its like buying warmoth parts

    but with more options, higher quality, and less cost.

    and im doing the body myself. just getting a fancy blank :)
     
  5. Nice bass, I like your idea about using the copper plating for the sheilding, did you do that for the pickups as well? And I think that I might just have to steal that idea.

    No, in the end, we didn't. Fitting something as big as that into the tight cavity was a major pain in the @$$. Also, these p-ups are humbuckers, which are not as noisy as SCs; also, they appear to be shielded (under all that epoxy). Without the shielding in the p-up cavity, it was absolutely silent - so we decided it isn't necessary.
