Instead of increasing the impedance to something that similar to a microphone (I believe around 200 ohms) as we do with the AS104, the transformer would have to increase the impedance to something similar to a traditional pickup (around 200.000 ohms). That's a thousand times as big an impedance, and hence, the transformer would have to have around 32 times as many windings as the AS104 (since the impedance increases by the square of the number of windings, and the square root of 1000 is around 32). So, in order to get an output impedance similar to a traditional pickup, we're looking for a transformer with 32 times as many windings as the AS104. The AS104 has 500 windings so that would mean that we need a transformer with 16.000 windings (32 times 500).

I might have made one or more mistakes in the above, but unless I'm far off, that's a lot of windings. I don't think such a transformer exists. If I'm wrong, I'd like to know.
