Recommendations for quirky spare-parts project?

[Mikdu]

Just finished building an Elam251 clone into a T.bone donor body, and was left with its insides. I was wondering if there are recommendations for projects to use the capsule for. Looking for something quirky and characteristic, as the capsule isn't great to begin with. I tried searching the forum, but couldn't find anything. Thanks y'all!

What model is the donor microphone?
T.Bone SCT-800?

Yeah, SCT-800, so the capsule is a generic 32mm K67. It also has the transformer left over, though i am not sure how useful that is to re-use.

To reiterate, I'm looking for a weird use case for the parts. One idea was to either add some sort of distortion circuit, or a compressor circuit like the SSM2166 into it.

Both the capsule and the transformer are good.
The stock sct800 circuit is relatively flat.
I really like the capsule.
You can make a cheap Shoeps, in any body you have, with parts at hand.
Or a circuit that also uses the transformer.

You can do whatever you want.
It's easy to distort classic circuits
It's easy to do weird things. And it's exciting!

Thanks! I really did not like the original mic, i might imagine it working for distorted guitar amps, but not much more. That might also be just me speaking after AB:ing it against the ELAM clone, which is in a different level alltogether

Yep!
My mic building just is not quite at the level of designing such circuit from scratch, which is why i thought there might be some projects to use as reference

Yes, you need to be a little more specific. Many of us have experienced all kinds of strange circuits

Basically anything involving the capsule i already have. Simplicity and ease of finding parts is a plus!

You won't be able to integrate the SSM2166 circuit into your weird microphone because the Phantom can't provide the total current required by the whole circuit and I think you don't want to use an external source for the microphone.
You can instead overdrive the input jFET, from BIAS, using a jFET with extremely low Idss, using a Highs polarization voltage for capsule, etc.etc.

@Mikdu
You can build a km84 style circuit using the sct-800 transformer which has a 7:1 ratio according to @mihi_fuchs :

You can add a DC/DC converter to increase the capsule polarization voltage
