So basically you ask him to make a bass, just not assemble it? Thanks again for the kind words! Sub: 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 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.
